I would rethink your position on this. There is no maintenance or safety related reason to service regulators annually, unless you are using it almost daily. Manufacturers slap this annual requirement on buyers to get them in the shop more often, and quite honestly, to inflate the perceived value of the 'free' parts programs.
I suspect you could buy this reg online, use it for several years (if you take care of it), then get someone to service it, then dive it again for several years, etc. It really depends on how often you dive, but most well-made regulators will go at least 100 dives, usually more, without needing service.
The warranty for regulators has very limited value in my opinion. The good ones rarely need warranty service, and there are lots of manufacturers that do not require annual service to keep the regs in warranty.
The one thing about your first post that raised an eyebrow to me was the statement that this reg is cheap because it 'came from a lost shipment' (or something like that. To me that smacks of 'it fell off the back of the truck' old cliche about moving stolen goods. I would ask the seller outright, are you 100% certain that this was not a stolen regulator? Because I personally would never buy stolen goods. I might be making a big deal out of nothing, but it did cross my mind.
