There used to be a free program called Fregen which lets you use your PC. I believe most had to buy a sound card and even an amplifier if more amps were desired. The cost would be around what your Godzilla cost. I think they are also limited in frequency but sub harmonics could be calculated and used on your PC. I thought about going this way but decided that I had enough money to buy the GB-4000, it has a carrier frequency so even with 240 volts and a 10 amp amplifier I can't feel any shock. It also has a bunch of treatments pre programmed and I still can use sweeps or enter my own program. Cost when I bought was around $2000 including the amplifier. Brickey
