S&B has recently had some pretty big price reductions. There's a company in Denver, Co.that sells S&B, that can VERY likely put you into a brand new S&B within your price range. So many folks rule out S&B right away because of the cost. I understand that, but in this market, at $2500, it is very possible. Another amazing scope that can definitely be had in your price range is the Vortex Razor. Don't be afraid of pre owned. With the warranty being what it is, buy it pre owned and drive on. The Razor is a great scope, and very likely my next big glass purchase.

To give you a frame of reference, I shoot a S&B PMII 5-25 on my GAP-10. Even having the Schmidt, I'd look at the Razor.

Just my opinion and thoughts. Hope it helps a little.
