Bushnell Trophy scopes can be had for right around 100 bucks. Mine is a 1.75-4x32 and is really nice for the money ($99), My buddy has a 3-9 and likes it as well. Or spend a little less money and get a bushnell banner. They work but I feel the optics are better on the trophy series scopes.

Mine is the Circle X reticle, they also make a 1.75-5x32 with a duplex reticle. For around 100 dollars I would stick with scopes at 9 power or under. Even a nice fixed 4 or 6 power would work well.
