I know there have been a lot of threads on these regulators. I have to purchase a new reg setup within a week and I'm pretty much stuck with scubapro since my LDS only sells and services SB regs. I don't care about price and am only diving warm water and want the best setup possible. Are the bugs worked out of the X650 yet? If so, I would prefer the X650. Anyone out there have good results on the new reg? Any thoughts or advice would be extremely appreciated.
