I'm in Calgary, too, and actually got my first stuff from Chinook (Cantina table/chairs, Nadon's Nook, Greedo and Hammerhead)... think I might've cleaned the store out, actually, as all that was left was Hasbro stuff.
Know what you guys mean about Another Dimension. The store is intimidating a bit for some reason, maybe because the clerks behind the till are raised a bit but I don't think it's intentional. Once I made conversation with them or whatnot they were friendly to me. The prices, though, are too high (Sideshow price plus $25 - $50 on top). I've still picked-up a few things from them because their selection and display are first class and it's nice to wander around in there. It's been a while since I've dropped by Phoenix but I'll give them a shot, I think. Just used Urban Samurai Hobbies for the DX10 and the price was great and delivered quickly, once it was in stock.
