Thanks for all the feedback guys! Great to hear what people think and get other ideas. I'm going to try to address everything in one post, so I'll apologize in advance for the lengthy response.
1.) Death Star Setup
This is definitely the display I'm most excited about, so glad to see so many others excited about it. The Blue lamp has random streaks of lightning running through it when turned on - very much like the core of the death star in ROTJ. Doesn't show up well in photos, but the very first picture kind of shows a "bolt" of the lightning. I added the Falcon under the ultarama display and the shuttle will back up to the vintage playsets, so hoping this one doesn't look too crammed in as well. Need to find something to cover the back of the front display as well - looks a little odd to see wood paneling along one wall of the death star. Maybe I can sweet talk Jay into printing me up a cool poster to cover it.
2.) East Wall - All Figures from POTF2 through current
Yes, I have thought about just displaying some of these figures and/or organizing them by character/movie/etc. Thing is, I'm a completist and one of my personal collecting goals is to have one of each figure (including variations) in that display. Only showing some of it kind of goes against my nature and to be honest, I really like having a visual display of all the figures in the order they were released. I'm always astounded by how many figures have been released since '95.
2A.) Risers
I have thought about risers and will probably upgrade to this someday. For now, I've found the clear risers to be just too expensive. That display is about five feet high by six feet long, so buying clear risers at $10-20 per linear foot seems pricey. I want clear ones because I don't have lights on each shelf and its nice to let some of the light feed through the shelves. I know there are a few sites that sell risers in various sizes. I've also heard people having luck with spice racks from Target/Wal-Mart.
2B.) Detolf
I bought two Detolf cabinets back in the day. One is clearly visible holding the Legends figs, but you'll notice it has no door...I took the door from this one and all four sides of the other one to make the clear shelves that all my loose figures are sitting on. I have pegs in the sides of the wood to hold the shelves as well as ulterama columns for support. As for the remaining Detolf, I have three extra shelves from the "spare detolf" and am using two of them plus the original three in my remaining Detolf display. But how to support those shelves? I thought about 4 column supports (wood or PVC or something), but that wasn't very stable. Then I thought about drilling in the metal frame and screwing in a piece of plastic coat hanger to create extra shelves, but didn't want to pull them all apart to drill and thought it would still look junky. So, I wandered endlessly around Menard's seeking an answer until I came across some metal stands in the grilling department. They are about 4" x 4" and sit inside a grill to hold chicken up off the grill. They were exactly half the height between shelves, so I put a few clear rubber bands around the top pieces for traction and viola! instant shelf support. It takes up a chunk of the bottom split shelf, but the added bars actually provide additional support for figures to lean on. I'll try to get closer pictures of these next time I update.
3.) South Wall Displays
I'm going back to putting all of my loose 12" on the top shelf. I have a bunch of packaged 12" behind them, which kind of blocks them out, but I tried to make sure that you can stil see a portion of each. The key to this section is a way to hide a vast amount of carded figures in a tight space. The entire bottom section is dedicated to banker boxes of carded figs, so this display is about three feet deep. Middle sections create additional storage with packages in the back and a diorama in the front. The layout of the boxes in back are pretty much determined by what fits in the space.
3A.) Clonetroopers
This section will be redone once I have a lose AT-TE. Not sure if I can fit all the existing clones along with that, and I have about 100 more (including purple ones!) that could go into it. Interesting to hear that people liked the mix - I felt this set was a little messy without colored squads perfectly lining up, but I did try to keep red detailed figs together, yellow together, etc.
3B.) Hoth Battle
Redoing this as well. I'll be adding at least two of the Target UBP Cannons to the Rebel side, but hoping I can still fit in the trench. One of the Walkers will be going as well - this was just a way to store all three of my lose ones. I had one loose and 4 boxed, so I opened two more to squeeze them in. One will go into storage and I'll add one or two chicken walkers from the UBP. Hoping to add some more uneven snow terrain as well. Any ideas?
3C.) Endor Battle
You guys didn't see it, but in ROTJ, the Rebels sent in 500 Rebel Commandos to take the bunker. They're just slightly off screen. Okay, got a little out of control with commandoes as I added to this one. I'll be taking down several commandos and adding a bunch of mix and match ewoks from UPB and TAC two packs. I also have a gazillion Biker Scouts to add in, as well as a few more stormies.
4.) The Room
This is a basement "bedroom" with no windows. Its about 12x14 I think, but I'm limited to just this room and a small section of an adjoining storage area, which is also holding a bunch of comics. With displays on all four walls, it definitely feels much smaller, but I'm not sure ow I could lay it out differently. You can walk all the way around the center display, but I'm definitely at minimal walking space.
5.) What I Collect
May look like a lot, but I really try to just stick with 4" Hasbro Star Wars figs and ships. I get one of each carded, one of each loose, then extras for displays. I have all of the Hasbro 12" figures boxed and maybe half of the loose, plus most of the SSC 12" figs. I also collect Galactic heroes, Kubricks, Marvel Legends, and Transformers, but I'm not a completist on any of those. Back to Star Wars - its not shown, but I have one or more of each vintage figure loose (excluding Blue Snaggletooth) and about 50 carded vintage. The loose figs are going in the front display and carded vintage are in acrylic displays in the next room.
Thanks again for the great feedback & please keep it coming! I appreciate all the advice. Hope to have some new photos soon!
