Bushnell elite 3200 would fit into your budget and is an excellent little scope. I have owned several and not one hint of problems, only knock I can find on the elite is eye relief and styling of their 50mm objective models. You never said what cal of gun you plan on topping with the scope but from 3006 down it will be just fine for most people in eye relief. If it is a healthy kicker or magnum you may need or want a bit more!

Mounts are very important, the guys laugh when I put a $200 scope on with $75-100 mounting hardware but maybe that is why they have problems with shift & I don't! I only use leupold bases and rings, their are others that are equal but these have treated my very well so I stick with what I know works! Bonus is if I want to upgrade my scope I need not worry about what is holding it tight

Good luck!
