And to ditto JamesP, if you do buy this machine and do try using it to test your embedded systems, first time use old obsoleted boards. Lightning strikes onto anything "directly" will probably proof lethal to the device. Better to set the generator up outside and let it strike the power grid - so currents are conducted into the bldg and onto the board indirectly.
