Just looked at a couple of possible sites; like you, I'm glad I got my 452's while the gettin' was good.FYI - JET Guns was the first place I checked - no luck. Even CZ Custom is out. I'm trying to locate one for one of my 4H kids. We've found a dealer a couple of hours away but he wants $475 for it, plus shipping.
I'm sure glad I picked mine up a couple of years ago.
