wmspdi:I had the same problem with Scubapro. I solved the problem by switching to Atomic Aquatics regulators. I have 3 M1 rigs (one traditional and a pair for doubles). GREAT regs, 2 year service interval (Z series one year), and no requirement to have the regs serviced based on the calendar to keep the warranty in force. Atomic's service interval is only "recommended", but you may wait and have them serviced when they really need it if you like. BTW- they don't freeze up like SP!
