If you are ok with only spending $100 take a look at the Romainian trainer.

Scroll down a little to see the gun. They aren't much to look at but have a great reputaion and if you don't mind refinishing the stock can look pretty nice. For info on 22's go look around at
http://www.rimfirecentral.com/forums/index.phpThey have catagories for most brands of rimfire guns, lots of good information.
My favorite bolt action 22 is the Remington 580 and 581, same action as the Remington 540 but more in the economy range.
CZ makes one heck of a 22 also. You get a lot of gun for the money.
But do check out RimfireCentral, everything you ever wanted to know about rimfires.
