I have a Doucet C box. It is very nice, although I don't have anything to compare it to, other than the Hohner 114 that I started on. I think it's well made and sounds really good. I got mine for about the same price as the eBay one is currently up to, and I have to believe it was a bargain.
Mr. Doucet seems to go by the name 'John', although you often see him referred to as 'Elton'.
