I still see the Bunker and that one set with some warriors, traps and stuff, here and there.
If you have K-Mart stop in... Or Sears Grand. They sometimes have older sets hanging about.
Also, check toy shows and Craigslist. For some reason, Craigslist has old Lego sets on it here all the time. Not REAL old, but OOP and for retail or even less, probably bought on sale and wanting full retail now to net a little $.
The local Toy Show has Lego guys hanging around now all the time too, so I imagine any you guys have in MN would be similar.
Lego Star Wars IS indeed the superior Licensee at this point. Sideshow's a close second with Hasbro (when they're making anything) close to SS I think. Both those have heavy flaws.
I think if someone only was into Lego Star Wars stuff, they'd be a happy as hell collector though.
