Are companies like Vada Energy, Alexis, and Hydrotech USA considered "Corporate Sales"? Why does that seem to be looked down upon here? The technology is already "Open Source". What if I just want to buy something that looks a little more, "Packaged"? I realize that this is a hobby for a lot of people, and I totally respect it, but if I might be so bold as to ask, of the three mentioned, which one is more efficient per cost? I am seriously looking at getting a Vada Max 1400 kit with the EFIE connecters. any advice?
