I posted about a year ago asking if it was still possible to get my Scubapro MK 7 with 109 and 108 second stages serviced (though at the time, I didn't even know what second stages they were). I recently got around to thinking about it again and sent the lds an email a couple of days ago asking if they could get parts and for a rough estimate. They replied with : first stage kit $36, and 2 second stage kits at $24 each, plus $70 labour (their standard annual service fee). And add to that an inflator hose and a port splitter to add said hose (that the shop guy said he'd have to find out if he can get, though the all-powerful internet tells me they exist) and possible replacement of the hoses that are already connected, I'm looking at like $200 or more. Now given that this reg has not been put on a tank since before I was born (i'm 21), I have no idea how well/badly this reg breathes and I don't want to put a bunch of money into it only to dive it once or twice and find that a low end new reg will breathe better. Can anybody give me an idea of how it compares to newer regs? If I do go ahead and get it serviced, I'm a bit weary about spending $144+tx every year. Would I be able to get away with every second year or having the tech look it over every year and only changing what's necessary? (I've never had a reg serviced before, so don't really know how it works) Thanks.
