Ok Mike, so if it's not Very Profitable Indeed, could it be..Very Private Individuals:)Just kidding Mike you have always been great to deal with on parts and tech support.

Yup this is Weisfeld Jr. and don't worry, Mike isn't going anywhere... the poor guy just wants to retire and go fishing at this point but I'm not letting him! Still plenty of turntables to be made! :)
