The CZ 45x bolt-action .22's are quite nice for the money. Probably the best bang:buck in a new bolt action under $1K.
Above that, Anschuetz is hard to beat.
But don't ignore the used market. There are good US-made .22 bolt rifles from the 50's and 60's that were quite good. .22's are hard to wear out - a good .22 bolt action rifle has a barrel lifespan in the 10's of thousands of rounds.
