I must warn you, Brian, that these are extremely addictive (or at least I've found them to be so), and even if you tell yourself you'll just get the OT sets or only get the main characters, you'll quickly find yourself saying that 10 bucks isn't so bad for four little figures, and then BAM!: your entire apartment is overrun with the little bastards.

The Hoth sets were what got me started, and now I've gotten every set that has been released, many of them in multiples. I have enough Utapau Clones, Snowtroopers, and Hoth Rebels that I could probably take over a small country. Watch out Guam!

Since I love this line so much, yesterday was major thrill day for me. I went out of town on a movie road trip and found the new ANH sets at a Wal-Mart and a TRU along the way. Picked up one each of the Droids/Jawa/Luke/Ben and Commanders sets, 2 sets of RFTs (which don't suck in this incarnation), and 3 sets of Stormtroopers. I think it goes without saying that those will be the first of many Stormie and RFT sets I'll be picking up over the next few months.
Quick notes on the sets:
-The figures all seem slightly larger than the 2006 figures, both in height and bulk. This isn't a bad thing, mind you, but it's just very visible when, say, a Stormtrooper is standing next to one of the 501st Clones from the Order 66 wave. Vader and Leia seem to be comparable in size to their Hoth counterparts. It just seems to be a PT-OT difference in the way that the Hoth stuff was slightly larger than the Utapau and Kashyyyk stuff (Wookiees excluded).
-Vader and Captain Antilles DO in fact interact with one another. While the bases don't interlock, they are sculpted in such a way that they can be lined up almost perfectly. Vader's arm can be lifted into place around Antilles' neck, and Antilles arms can be positioned to where the non-pistol hand is holding onto Vader's wrist. Just an interesting little tidbit I'd been hoping for that Hasbro really came through with.

-The two sets I got at TRU (1 RFT, 1 ST) each came with a mini-30th Anniversary Collection catalog if you're into that sort of thing. Kind of like the TSC catalogs that came in the basic action figure line last year. The sets I got at WM, however, came with the old big TSC 2006 catalog. Weird.
