I've got a HS Victor & a S&W '41 (both old, used when purchased) -> they're each excellent shooters although somewhat ammo sensitive. My own research prior to buying a .22 LR pistols put these two models in my 'top 3', along wiht the Ruger MK II mentioned above. All pricey new, but lots of used stuff available that won't break the bank. I have not heard great things about the newer S&W rimfires ...
added: I've also fired the Baikal IZH-35 above (club gun) -> as close as you can get to a real competition pistol for <$1000 -> 5 round mag cap, and not suitable for 'field' use (not that we care about that in Canada...)
