You might find a used Vortex Viper in that price range, I have a PST 4-16ffp MRAD model and really like it, mind you i haven't used a nightforce or s&B, but i will probably never at their price point. Where i shoot allows me to go just beyond 1000 yrds and everything is repeatable with the tracking and scope seems clear enough to me. Has illuminated reticle, unconditional lifetime warranty, seems like a win to me. One thing i will advise is to try and get a scope with matching reticle and turret values, MOA-MOA, MRAD-MRAD it will make things a lot easier.
