There is a "Busato" on French ebay currently selling for 100 euro or so. The price is only going to go up from there. I put Busato in quotes as I don't know truely if it is a real Busato or a Mirecourt luthier's copy of a Busato. Alas, it looks pretty cool even with all of the work that needs to be done.
