I know, right? I saw those pics and was blown away and then cried a little inside when I saw the price.
Like you said, that two piece tank thing that transforms into a base and Mech/walker thing is so bad-ass. I'd love to see this stuff get picked up into wider release somehow to bring the cost down.
Very cool stuff though. Might have to keep an eye on more of these "designer" 3.75" scale companies that are out there (like the Aliens thing you were talking about the other day).
