Have never really gone after top end 22 makes as mine have to be workers, and it simply isn't worth using expensive or collectable weapons out of the truck etc.. too easily marked. Sold a brace of delightful Winchester 94/22s (22LR and 22 Mag) in mint condition not so long ago - simply because not prepared to mark them.
Of sporter 22s of reasonable to good quality, the two I'd suggest would be the Norinco Em332 for about $500 these days, and the Weihrauch HW60J for round $1000. Of 100 or so sporter 22s I've played with (standard barrel) the Em332 proved most accurate off the bench at 100 meters, averaging 0.6" for 4 consecutive groups with PMC Match (black packet). HW60J also precision shooter.
