You may be looking at the CZ 452 American, which costs a bit more than some of the basic Scout, Trainer, etc. models. I have one, and it is very nice.
I am no longer up to speed on all of the models, but some CZ's have a 11 mm European dovetail scope mount, and I think the American (comes with no iron sights) has regular 3/8" mount.
Some of the models used to have a rep as being a bit difficult to mount a scope on because the (excellent) rear sight got in the way and was hard to remove or rise above. If you wanted to mount a scope, back when I got mine, the American was the easy way to go. For iron sight shooting, other models are the ticket.
I could be behind the times on this, so you may want to check out
www.rimfirecentral.com. Go to the section on CZ's. Look for the sticky at the top of the CZ section titled "CZ 452 Model Specs".
It is a pretty active board, and the folks are pretty helpful (like here). Ask them all your newbie questions. I did, and still do.
