I have the gunship but I haven't built it yet. I have a few larger sets that are still boxed and waiting for me to have the time to build and space to display them. It's easier to find the few inches of shelf space for an A-Wing rather than the 6211 ISD.
I haven't decided about the AT-TE. I didn't get the first one, but I was in a mostly dark age when that one was at retail. You'd think that would make the new one a must-buy, but I'm still undecided.
One set that I have no intention of purchasing is the Twilight.
