I think a serious .22 needs a serious scope. I gave up on the cheap $29, 7/8" rimfire scopes years ago.
On my two .22s with scopes, one wears a 2x7 Leupold. The other has a 1.5x6 Fujinon. Ideally, a .22 scope should be parallax-adjusted to 50 yards, but I think the usual 100-yd parallax setting is OK for casual plinking and squirrel hunting. Now if you shoot a tricked-out Anschutz(sp?), you already have your scope....
