I have a MagnaZap (http://www.webdeb.com/zapper/magnazap.htm) and it does help my skin parasite condition.
Are you referring to Curatron PEMF devices when you mentioned $3,000? I wrote to the company and someone replied, saying PEMF "will kill mites when you use the XP model with the very high energy coil by creating internal heat and electrical currents under the skin." Do you agree?
