The Admiral Kuznestov is a monster! There's one built at the LHS, and it's one big ol' pile of plastic, to be sure. The Nimitz is even larger!
And to continue their "bigger is better" modelling philosophy, Trumpeter just released their two new 1/32 Avengers! Lots of plastic in those boxes.
I'm still seriously thinking about getting the 1/32 Su-27...
