Mambo Dave:From what I can tell, the DR's were developed in cave country, for caving, and they're inexpensive for such a good reg.
I bought 'em because the parts and service instructions are so readily available.
Developed in cave country? Nope.
They are a chinese knockoff of the Apeks regulator.
Is this a bad thing? Not really. I had both and serviced both. I just sold my diverite though because having to keep 2 service kits all the time got to be a hassle. I also feel that the parts inside the Apeks were slightly higher quality.
Would I suggest a Diverite, hell yes for the price. Overall it is a "buy". It's based on a solid and well proven design.
