I have EL inverter modules that convert +5 to the required voltage and frequency. I charge $6 each and include shipping within the continental US. For shipment elsewhere it is $5 per module plus whatever the actual shipping costs are. I have sold hundreds of these to PIC list members in the past, with no complaints. These are all new commercial units and usually retail for about $30. Three pin: Gnd, +5, and HV AC out. Fr.
