I might check out the HOG regulators, . . . .
DeepSix has the same philosophy that regs should be user-serviceable as HOG. Not surprising, as the same guy who founded HOG went on to found DeepSix. Check out the threads in which DeepSix regs are discussed. I have HOG and am coveting the DeepSix. It's very satisfying to service your own regs.
