Any of the Bushnell Elite scopes should hold up. I have a 3200 3-9x40 that as been on every thing from a 204 Ruger to a 458 Win Mag. This included more than 500 rounds on a 375 H&H. You can find the 3200's for under $200 depending on the power range you're looking for.

If $500 or so is in you price range, I think that you could find some of the Bushnell 4200 line, or some of the Leupold VX-3 scopes that would work for you. I really like Nikon scopes, but I'm not sure about their durability.
