but if us "lay-zappers" simply either make our own cheap zapper according to Clark's specs, or if we "legally" buy any of the many prefab zappers still available out there, won't we basically get ENOUGH benefit from this contraption? I mean, I don't understand why they don't shut ALL zapper makers down?? And for that matter, why don't you just make Class II machines, ParaZapper? After all this exposure and press, you'd be able to make a ton of change! Ha! IMHO, it's all about design... They all seem to do basically the same thing...
