I have a Marlin 882SS that is a great little rifle for varments. If I do my part 5 rounds in a nickle sized target at 50 yards. I would suspect they are about $200 or so used for a really nice one. Mine came from the factory with fiber optic sights. A fixed 4X scope is all it needs if you think it needs one.
The other would be the Savage 93 with the accutrigger. We have them in .17HMR and a similar MARKII in .22LR. I like them almost as much as the Marlin and the trigger probably makes them a more accurate rifle.
