Another vote for Sig here. I'm surprised no one's mentioned the Somethin Extra. This is a laser cut kit, awesome build, plenty of threads here on RCU regarding it, and a whole lotta fun to fly. Strap a TT Pro .46 on it and you'll have a blast. I have both a Mid-Star and a SSE and recommend either one for what you're trying to do. The Mid-Star is a bit "tamer" than the SSE IMO.

First pic is the Mid-Star, the second is the SSE.
