In that price range, you can look around for an older Japanese scope. I have one that came with a used Rem 700 that is marked Mauser and made in Japan. It is a really nice scope. You might luck out and get a Leupold 6x for that price, but don't wait around if you see one. K6 Weavers can usually be had for that kind of money, but lately the 6x scopes have gotten scarce. The Vortex might not be a bad choice, but I haven't looked through one. I am also a fan of 6x scopes.
