I used HOG regulator myself. Their quality is as good, if not better than any big name out there. I would have no problem recommend them to anyone based on that aspect. However, I do think local support is very importatn especially for newer divers. Local support could mean you have a regulator tech friend that you trust, or a LDS that will support HOG, or the diver him/herself. The last one is not likely for a new diver tho
Sending out the reg for service once a year is not that bad. But what if the reg come back with minor issues. Or even more likely, 2 dives after coming back from service, something needs a small adjustment. Nothing is worse than sending the regulators out for a minor adjustment, could have been a 15 minutes job at a LDS, but now a 2 week turn around time.
Have that said, if OP can get local support, HOG regulator is very good value for the money.
