Given any thought to the CZ Kadet pistol? I've got the adapter for my PCR, I love it. It has some very nice adjusable sights, probably not quite as good a trigger as the two you mentioned, but it will improve greatly with use or a 15# mainspring, my PCR has one and I have never had ignition problems with it, 9mm or .22, ever. Also they are not picky at all about ammo, and they are a fullsize, all-steel gun, if that is a plus for you. Not sure what the other two cost, but the CZ should be around $500.
Just my NSHO.
