CZ firearms are excellent - serious tack drivers. Here we call them "Brno" - after the Czech town where they're manufactured.
I have a ZKM-452 with sound moderator and spare 5-round and optional 10-round magazines. Thoroughly love it - never misses a beat and accurate as hell even with the standard iron sights over various ranges.
Build-quality is excellent, finish superb and it's evident it'll last years with the minimum of maintenance.
Bought mine brand new, cost the better part of NZ$800 over here. It's my second - bought after the first got stolen. If the first hadn't been a superb firearm, I wouldn't have bought a second.
It's nothing complex, just a good, basic well-made rifle, not too heavy but not flimsy, nothing flimsy or finicky about the action either, great positive feel on the bolt, crisp clean trigger-break.
I heartily recommend CZ rifles from my experience - and not one shooter I've met has given me hell for getting one, back-yard plinkers and serious small-game hunters alike have said "oh, a Bruno, sweet-as!" Their rep is spread far and wide.
A great rifle for experienced shooters as it won't disappoint and a great rifle for inexperienced shooters as it's reliable and accurate.
If you're learning, though, get decent quality ammo to put through your rifle so you know the bullets should all hit around the same place - with a decent rifle and decent ammo, two probable causes of inaccuracy and inconsistency are minimised. Unless you're on an indoor range, you won't be able to do much about the weather. After that it's practise, practise, practise. Great thing is: with a .22, even firing costlier high-quality ammo, it's very cheap to put a few hundred rounds downrange.
And a hell of a lot of fun.
Best of luck in finding the rifle you want, have fun and be safe.
