I have owned three 22 revolvers:
1. Heritage Rough Rider Combo, SA, 22LR/22Mag - great, fun gun for the money. I paid so little for it I scratch my head wondering why I ever sold it. Makes a great trail gun when you don't want to beat up a more expensive piece. If I see a used one for $75 like I did once, I might just take a chance.
2. Taurus 94, DA, 22LR - hated it. Extra crunchy trigger and lead spitting did NOT earn it any points. Sold it.
3. S&W Model 17-0 / K-22 Target Masterpiece. This and the S&W Model 18 / Combat Masterpiece and are my absolute favorites. Both are getting harder to find, particularly the 18s, but they can still be found.
My K-22 is an absolute joy to shoot. It cost between a new Taurus 94 and a new S&W 617. It is a fantastic bargain, when you think about it that way. For me, it is nicer than the 617, since the no lug barrel balances so much more naturally. My K-22 always comes to the range with me, and it is always a big hit with everyone who tries it.
