consdider any quality scope that has the following:
1) minimum 3.5" eye relief to prevent "scope eye"
2) Wide FOV, I like the 1-4 power range scopes, as they have the widest FOV for shooting at very close range at 1x power. Higher powered scopes will show you nuthin but brown fur at close range, making quick shot placement difficult.
3) Shotgun/Blackpowder type parallax setting--50yds--the typical rifle scope is set up parallax free at 100yds, which means sighting in at closer range (you typically want to sight these in at around 50yds to avoid "windage" errors from wind drift at longer ranges) can get frustrating, as the crosshairs may "dance" on the target.
My personal favorite is the Bushnell Elite 3200 1.5-4.5x32 with firefly reticle, although its a bit above your price range at between $150-$180. Its well worth it, as it is durable, and has the rainguard lens coating which really does work. It also has extremely good light gathering ability. I am typically able to see clearly well before and after legal hunting hours, when only shadows can be seen with the naked eye.
