John,
I am certain that your 842S must be a very nice horn. However your price expectations are a bit north of where they should be. New horns are very available (compared with Sterling or Hirschbrunner) and can be had for between about $4900 and $5500. Recent eBay's (that I recall) have been in the $4000 - $4500 range.

P.S. Contact "gregeuphonium" on www.dwerden.com. He is looking for just such a horn. He might also be "euphonium410" on this board.
