The AT-TE is what I bought... It's perfect. I honestly am shocked how nice it is, and love it.
I skipped the Falcon, partially due to its size, partially due to it obviously being underscaled and my "rule" as it were, and partially just because of cost. Not that it isn't a decent price... I'd call it fair. But ultimately if it creeps lower I'll try to pick it up. That was my main issue with picking it up now. $150 just isn't there in the old budget.
As far as new big stuff...
I'd like to see Hasbro tackle a to-scale Slave-1, AT-ST, a To-Scale X-Wing, Y-Wing, and maybe B-Wing, and from there I'm not sure. Those would ultimately make me very content... The SNowspeeder too, but I didn't list it as it needs decreased in size to be proper, not increased. The others would need beefed up a bit, but I'd easily pay $60 or $70 for any of them to-scale (save for the AT-ST... It's not that large).
Dressel, the "Snail Tank" Droid really isn't that big... They're pretty tiny vehicles that could work easily in the $20 assortment so long as the two sets of side-treads are removable. It's a fairly small vehicle really.
