Hey guys no need to spend so much for a power supply. All you really need is a Variac which you can find on e-bay for between $20 and $60 and a transformer that is capable of 30 volts/5 amps or 42 volts/2.5 amps. These should cost no more than $20.
As for wire I sell Rene in .014 for $25 for a 50' spool which should last the average modeler a few years unless they are producing hundreds of wings. Rene is the best wire we've found and we've been using it for production for several years.
