We just had our 1-year-/~25-dive-old regs serviced for the first time and wanted to compare the experience with that of others out there. We went to a reputable dive shop (Ocean Enterprises, San Diego), who quoted $55 service charge and estimated $10 in parts, per reg, should be about 130 (who knows even if this is in expected range?), ended up at 155 with new flow control element and flow control filter for one reg, not to mention o-rings that were about a buck a pop. I had that unpleasant Am I being ripped off? feeling that one often gets in a car repair joint and though this would be the best place to ask. (I know a lot of hard core folks will tell me to DIY --would especially cure the loss-of-control feeling!--but it ain't happening, at this point anyway.) They did all the right things--itemized costs, gave us our old parts back--I just wondered what others' experiences with this were...thanks for the input.
