I'm kind of at a loss here --- What do you think isn't going to last?I'm kind of in Penman1's camp. If someone would build a component set I was not afraid to sell, I might try to get into the business. As it is, I give mine away, and I hold my breath for each one, wondering how long it is before it comes back with a problem. I just can't imagine selling hundreds of these things for real money, knowing they are not going to last. I know a lot of people do it successfully, but I can't figure out how.
