I came across an eBay listing for a dual tube unit similar to the Hydro Super 2. It has 316L Stainless tubes, and 316L stainless plates, and everything else, nuts and bolts are your regular grade stainless...

It comes in a complete package, priced @ $285 Shipped to your door. Seemed like a good looking kit, so I decided to give it a try. It showed up tonight while I was at work, and I plan to switch my generator out on my truck now, with this one. My first impression is that it is a nice kit. The generators look good, however I was dissappointed to find that taking them apart is going to be a chore as they are sealed shut using some kind of clear sealant. No biggie, I'll run them for a month or so, and pull them apart later to see the wear and tear....

Anyway, here's a couple of pics for you guys:
