Ammo is a little more expensive than for the Tok but I'd get the CZ82. Even my wife likes shooting that one. Easy to carry, smooth edges, good trigger, generally comes with two 12 round mags for a little more bang before reload...what's not to like. Plus they're newer and the civilian version (CZ83) is still for sale so parts are easy to find.
As fror the P64, the size is nice. The one I had had a real nice single action trigger after the spring job but the double action definitely left a lot to be desired. It didn't really hurt my hand to shoot but it wasn't something you wanted to target practice with.
