Savage MKII is always the answer to "budget friendly bolt .22lr".
CZ's are technically "better" guns, but don't come in the variety and can be double (or more) the price.
Are you looking for iron-sights, bull-barrel, ring-mounts, wood stock, target gun?
I've recommended this gun to many of my friends:

You can also do it without the bull barrel and with iron sights:

You can go crazy and get one with a rail and threaded barrel:
