Kimber, Weatherby/Anschutz, Anschutz, etc. are all really nice. And expensive.
CZs are really nice, and less expensive.
Marlin and Savage make some accurate, dependable, fun, American-made bolt rimfires for downright cheap, though.
Then there are used Winchesters, etc., and the Winchester Wildcat, which can be had for some great prices if you look around.
If you want a stand-in for a centerfire, Ruger makes exactly that: a gun with the size, proportions and ergos of their centerfires. The 77/22 is not inexpensive, though.
Old Mossbergs are possibly the best "sleepers." Their barrels are EXCELLENT, but the guns aren't the prettiest things and collectors don't go ga-ga over "Mossberg". For a good shooter for cheap, comb the gun shows and used racks for one.
