Hello Willie,
I found my Zu 103R on Audiogon, new in package, for $650, I believe it was. The seller had several of them, and was selling off the extras.
Soundsmith does good work, from what I've heard, but they are always back-logged with work, so you will have to wait awhile on a retip. Check around, you might find one at a good price new, or low hours on it.
Hope you make out ok.
Regards,
Dan
