Good for you,you will love it. CZ's are in short supply, especially the 452-453's. IIRC the trainer is the same as the Lux but with a beech stock. The 452-453 has an advantage over the 455 because it has better iron sights. It will be the very accurate out of the box, but the trigger can be made much better with lighter springs and shims for the sear.
The only negative I have seen on the CZ rimfires is the safety is backwards, but its no big deal.
