My 22 revolver is a Smith & Wesson Model 17. It's a 10 round with a 6" barrel. Generally, they are considered a Cadillac of 22 revolvers and they can be a little on the pricey side.
If you can't find the S&W, I would go look for a Ruger SP101 22. They are relatively new, and I haven't put my hands on one; but I do have a 357 SP101.
