I run a P68SC and as long as the paint is good I can run pretty well with the Phantom's and even the Snipers. Get whatever you feel is what fits your personality. Even if you get the old school P68 there is no reason you can not upgrade it by sending it to PPS or KPCS for some custom work to be done.
Rainman does some nice valve work and can get your shots per 12gram up there with the Phantoms. He can also powdercoat it and put a 45 frame from a cocker or mag on it if you want to gussy it up
