Over on eBay, The Cardboard Galaxy has some new (and new-to-me) stuff I was thinking about picking up. I assume this means you'll want them, too. And as I am part of the eBay affiliate program, these are affiliate links, so feel free to click often and buy things.

The Retro Death Star Figure Display Multilevel Playset is listed as being DETOLF-sized and looks like a mishmash of Kenner art from before 1980. It's pretty gorgeous, there's even a Millenniun Falcon painting in there. It's $50.

An upgrade set, the TVC Streets of Mos Eisley Accessory Set Backroom Base Arch Insert goes with the just-released Mos Eisley set. It adds a floor, some scenery, and a whole room. It looks like you can configure it a few different ways, which makes me think I need one and a couple more of Hasbro's set.
It's a lot like the one he did for Jabba's Palace/Trophy Room.
