Do you want a single action or a double action? Is this for plinking, something for the hiking trail, or as a trainer for another revolver?
For single action, skip Heritage, their warranty sucks. Ruger's is better, they make a Super Wrangler .22 Mag/LR convertible with adjustable sights and believe me, you want adjustable sights. It may not be the best single action .22 revolver, but it's certainly the best bang for your buck.
For double action you have the choice of a gamble with Charter Arms (their quality is bad these days), Taurus, and the Ruger LCRx. The Ruger is gonna run you $550, it's light as a paper clip, but it's a good shooter. The Taurus 942's can be hard to find and I have no idea how the triggers are on them, and the sights are inferior to the Ruger. The Taurus Tracker .22's are impossible to find and will cost a pretty penny.
Charters... people here who have owned them have had positive experiences, but those are from guns bought years ago. IDK how well Charter is making .22's now, I don't trust the brand's current production, but you could look for older models, those are higher quality.
