copper is expensive

There has been a rise in copper price. It is at a two year high now. People, this is important because Steven Gibbs HDR uses 200 feet of copper wire. That is a major expense. Fact is, producing the HDR is getting more expensive. Also, components are going up in price. Then again, the biggest problem is that copper is expensive. Steven Gibbs refuses to use aluminum which is cheaper in building his units, but I fear this may not always be the case.
