The recycle setup is pretty nifty, all right. We used them in a lot of the high end homes I used to work on. We'd insulate 'em like crazy, ends up being more or less an extension of the tank, though you're bound to lose more heat than the tank, per unit of water, even with top insulation. They make this stuff that's rigid fiberglass, about 2 or 3 inches in diameter -- much better than that black foam stuff you often see.

I can't imagine not having a cold line as well, I mean I could see the attraction but who wants to be scalded, all the time?

I'm going to have to look into this SharkBite stuff, I'm a bit skeptical though. Seems too good to be true.
