Less expensive can be good too!
I have two of the less expensive 22LR guns. A Heritage Rough Rider six shot single action and a Smith and Wesson 22A. The Heritage was less than $150 when I bought it several year ago and the S&W was a good buy at $225. Both shoot well, are easy to care for and lots of fun.
And the availability of 22 cal ammo depends on where you live. A local big box hardware store near me has dozens of bricks of 22 cal ammo on it's shelves.
Live well, be safe
