$150 is a good price for a CZ-52, (at least in my area) and one of my favorite handguns.
It takes a little getting used to the grip needed for it.
They _can_ be abit picky on some surplus ammo (namely romainian) , but new production S&B or FNM should work flawlessly.
I think everyone should have a CZ-52, and a TT-33
