Take a look at Bushnell's Elite 6-24 x 40 scopes. They're around $800 on the Bushnell web site, but Optics Planet usually has them for around $400.
Excellent scope, great clarity.
I think there is a sale / rebate going on right now, and that scope will eventually cost $375 after rebate. I'm thinking about buying another one for my .308 rifle.
