Mastro,
you're looking at entry-level rimfire target pistol shooting. You have budget limitations. If you ask me, there is only one answer: Ruger Mk II.
Good revolvers are lovely, but there's a reason why you almost never see them on the line at matches anymore: you have to learn to thumb that hammer back for each shot, and your grip will shift. No problem if you're plinking, but if you want to learn to shoot bullseye it will increase the difficulty.
Model 41 is much more costly, and not one bit more accurate than MkII, and there are lemons out there. I love mine, it's a sweet and pretty pistol, but I shoot my MkII just as well.
Hi Standards are classics, accurate and good-looking, but again pricier. I've shot more than a few, including the HD Military.
Can't comment on the IZH except to say that it is more costly too.
MkII is comfortable, accurate, reilable, easy to maintain no matter what some tell you (and doesn't even NEED disassembly but once in a blue moon), and it's affordable. I had a trigger job done, didn't cost much, and tha's all, except for adding a set of Pachmayr wrap-around grips. That was 21 years ago, and never a hiccup.
I think that for geting started, you just can't do better than a pistol which is accurate, easy to shoot, no worries about geting a lemon or a finicky feeder, and you can afford to buy it new. And if you're like many others, as the years go by if you stay in the .22 target game you'll accumulate cooler, fancier pistols but still come back to the MkII again and again. And when you do, you'll be surprised how well you can shoot it.
So that's what I'd do. Take it from ol' Khornet, who wants you to have fun and be happy.
