High Voltage vs Low voltage CS generation has been argued to death on the Silverlist.com forum and no consensus has been reached other than that we know they both produce CS that works well. I think currnet control is necessary on both for smallest particle size. The other other thing with High Voltage CS gens is they are a lot more dangerous to work with and not something I would leave running if I left the house where as I have no problem with my auto LV units running when I leave home. What HV CS gen do you recommend to folks who want to try one?
