Why the 7-ft. hose?
Brass-and-glass SPGs are nice, but so are the plastic ones protected by a plastic/rubber housing. Both last a long time.
$825 vs. $900. That's still a significant price difference.
The Hollis 221 second stage doesn't have a breathing adjustment knob. That can be a pretty nice feature. The Hollis 212 and the HOG second stages have it.
If you plan on getting a tech certification or taking an "approved" tech class, you would be eligible to take a HOG reg repair course. If you are a recreational diver with no tech aspirations, then you cannot take the course. I suppose it's a nice option if you think you might want to DIY service your regs in the future and you're going down the tech route. I find it strange that the company/TDI is so adamant about not letting recreational divers take the course.
