Check out: <http://www.eio-dot-com/componts.htm>http://www.eio-dot-com/componts.htm for Panasonic poly caps for mmc cap applications. They have 7,600 0.22 1250 volt DC poly caps for sale for $3,500. They might be willing to drop the price if someone wanted to orchastrate a group buy. Throw about 40 of these into a series/parallel configuration and I think you would have a very robust poly cap for dirt cheap price. Bert
