I recently picked up a Savage 22-250 model 12BVSS single shot (with the accu-trigger), topped it off with a Bushnell Elite 4200 8x32 scope. The rifle was a pretty decent price, though I can't remember the amount at the moment. Less than $650 though. The scope and mounts cost about as much as the rifle. I also like, but don't own, the Howa 22-250 with a thumb-hole stock. That's right around $650 where I am.

Took the Savage to the range, and I must be living right because it liked the cheap ammo. Winchester high-velocity 45 grain ammo, box of 40 for $20. After I got it sighted in I put five shots in a 1 inch circle from 100 yards (from the benchrest of course). It didn't like the Winchester softpoints as much. And, while its the first rifle I've had that didn't group well with ballistic silvertips, I'm hoping that was just barrel break-in and bad luck that made those group so poorly.
