I'd seriously look at the Vortex scopes. A 4-12 X 40 Diamondback with dead-hold BDC reticle with A.O is right at $300. If you want to step up a notch, look at the Viper 4-12 X 40 with dead-hold BDC reticle (and side focus). It is right at $400. Personally, I'd get the Viper between those two. It's a dandy. Another great scope is the Zeiss Conquest (3-9 X 40). Cabelas has them for $399.
