Well, since no one seemed to have an opinion on this topic, I decided I would have to just find out for myself -- so I ordered one today. The shop didn't have one on the shelf, but they did have a 612, which seemed very solidly built. The shop also had an entire shelf (an entire shelf!) of CZ pistols in one display case, so I had to spend some time drooling over those as well, though sadly I can't yet afford one. And shucks, since I was already at the shop, I also had to have a look at a 455 FS, a 455 Lux, a 527 Carbine, a 527 Varmint, a 712 S/A, and a Supreme Field O/U. Can't wait for my order to come in!
