For that budget I'd say Burris XTR 2. You can get the 3-15, 4-20 or 5-25. I've been loving my 4-20, and I got it for like $875 brand new after rebate (they have a $100 rebate thing going. I think it's still going till the end of the month or august, but I'm not sure).
Most people I've seen prefer the XTR 2s over the Gen 1 PST scopes, but the Gen 2 PST scopes are supposedly better than the XTR 2s, as they should be, they will cost about $200 more.
XTR2s have a good zero stop, they are tough, and are FFP, and come in both illuminated, and non-illuminated models, the non-illuminated ones cost about $100 less.
There are also 2 reticle options, SCR, and G2B. The G2B costs less than the SCR.
