There are several .22`s on the market, that are fun to shoot.
I chose the Browning International II, because I have both worlds combined in it.
I do target shooting as done at the olympic games. Single handed at 25m, but also like to plink a bit. Steel-plates are very fun to shoot with a .22, because you very little recoil and can really go fast on the plates.
I tried the Walther ?22 and didn`t really like it much. It`s very small, almost to small, and the trigger isn`t mine. The ruger looks similar to me.
If you are more into practical shooting, have a look at the GSG 1911`s.
Not too expencive and are supposed to be pretty good and accurate.
If you are more into plinking, fun shooting, the Browning oder Ruher MK Series are a good overall choice and cheap to get.
I paid € 169,- for mine (I live in germany).
You can also look at the FN 150, wich is the same as the Browning International II, only that it has a round bull barrell.
