I am also a fan of the Remington 552. My dad had one when I was growing up there is no telling how many squirrels and rabbits I killed with it.
My favorite, though, is the Browning BL-22. Bought one with my first paycheck from a summer job in high school back in '79 and still have it. Works flawlessly with all flavors of shorts or long rifles. I always knew it was accurate, but I put a 4X scope on it about 10 years ago and it really shows out now. The short throw lever, about 45 degrees, means you can produce follow up shots much quicker than with most other .22 lever guns because your thumb never leaves the stock when you lever it. Great feature.
