I have told this story before, but back about ten years ago I finally gave up trying to put together a "complete" collection of modern stuff. (I had all the vintage figures, minus a couple of the POTFs, as a kid and was never interested in completing a new collection of them. The modern line, however, held onto me with the promise of new figures and a "complete" collection.
So I sat down and made my own list of the figures that I needed in my complete collection, and stuck to it as much as was humanly possible. I also gave up on vehicles at that point--there's a whole rationale there, but basically I loved playing with them as a kid but never thought they displayed well among the figures.
Once I had a set of what I thought was going to be my complete collection, I went about designing customized shelves to display them on, broken down by themes (Imperials, Hoth, Cantina, etc.) I had a thread about those back then, but the links are busted. Here's a couple of the shelf designs I made to give you the idea:


And I was pretty satisfied with those...though I didn't put the finishing touches on acouple of them, and never built the Jabba themed shelf I wanted.
Since then I have moved, and had a couple kids, and I never got the office space back that I wanted. So these shelves are still packed away too.
These days I make cardstock and cardboard displays to sell as Cardboard Galaxy, and my collection mostly rotates through those new designs as I make new ones and need to photograph them. The latest thing I have been making is "archival displays" designed to show off the vintage figures on cardstock displays reminiscent of the Action Display Stand Kenner made for the first 12. Here's the "Empire Strikes Back" segment of that:



I have enjoyed seeing my modern figures broken down into the vintage equivalents, I like them set up this way lately.
Good luck Brian, and please share pictures when you have the set-up you're dreaming of!
