Update: FWIW, Just called two local shops that service DiveRite. One sounded unconfident and said to call back tomorrow when their head tech was back in to confirm. The second was familiar, no problem, but then goes "oh, you haven't bought it yet? I would discourage that if you haven't invested already" and filled me in that the murmurs are they may not be around too much longer in the standard reg business. Good for right now... but long term prospects aren't as promising. He said the part kits are getting harder, and some they no longer supply, and he hears they may be focusing more on rebreathers, etc. in the future He recommended I pull the trigger on something like APEKs instead which will be around for a long time and is just going to be a lot easier for me.
Granted, this is just one guy. But still.
Before we say there was a vested interest on his end, I should make clear: I told him there were no DiveRite shops in Portland so I'd be making a special trip to his store. By telling me to go with a different brand, it was a business loss situation from him as he indicated I could also find someone close to home to service me.
Sooo... I'll call around a bit more locally, but those first 2 calls were not terribly encouraging.
