I mean this with no disrespect, but I'm not sure I'd be willing to pay all that much for a g2g unless you wrote a "have these parts" list, and showed up, and walked me through my build, and first batch of bio. a lot of info on the web for those who can just read, and do.
I do however like the idea of having some sort of biog2g, and I'd definitely like to get a few engines around here runnin on the cheap stuff.
I need to get a few more of them running period...
consider me a probably if the work shop was low cost.
