If you're thinking about 10m match
The IZH is OK. Not great, but OK for the money. But if you really want to try 10m bullseye, what will happen is that you'll start with the IZH and sooner or later end up with one of the really good ones. They will run you $800-$1400 depending on design and maker. There are just about no good spring-piston guns anymore (I'm talking match pistols here); they're all single-stroke pneumatic or pre-charged compressed air. And they are exquisite, really.
Feinwerkbau, Steyr, Hammerli, Walther, Morini, and many others make superb guns. And they'll last forever with good care, and you can shoot anytime, without a lot of noise, and ammo is cheap. They're worth every penny.
I have a Walther LPM-1, a single stroke pneumatic .177, which I have shot almost daily for 7 years now with no end in sight.
JohnSka could probably comment here. Used guns are out there, and a good bargain. Also check out
