The S&B 3-20 PMII would be a nice fit....nice size without being too big, nice range in magnification, and awesome glass.
Been hearing good things about the Kahles scopes as well.
I have a few NF scopes and have been very happy with them. Better price point, awesome quality and durability, you just give up a bit on the glass quality (albeit not much)...3.5-15x50 is a beauty for the price.
