I think you miss the whole message of Bob Beck. Sure for the people whole just want to rely on the establishment to fix them, buying from a commercial suppler is fine. But what happens when the government finally bans commercial sales altogether. And what about those of us who like to tinker and really cant afford the commercial stuff, which is grossly overpriced. As for commercially sold generators, yes buying a ready made unit is fine for some, but again why is the price so high its little more than a few batteries and alligator clips. The wire sold for those units is again over priced. If the commercial suppliers were not profiteering it would be easier to support them.
