I have one of these in the cabinet too. Came with the set of ~1/144 AT-TE, Eta-2's & B-wing that I got from eBay. 1/350 is not one of my current scales, though, so I'm no sure I'll do anything with it...
While it's a nice size for medium ships, I've already got 1/12, 1/60, 1/72, 1/144 & 1/8000 going.
