Hey David. I actually didn't know there was a Gotoh version of the Stauffer tuner. Do you have a link to it or information? I know Martin makes them for their early Martin copies but I'm not sure if they sell them. I tried to find out but my emails weren't replied to so....who knows!
I use Rubner as my standard and Rodgers for special order. The Rubners are about $350.00 and the Rodgers at least double that (I just received an order from Rodgers and I'd have to look in my files for the exact price).
There's a fair number of European guys making Stauffers. Martin de Witte is one and makes his own tuners. He might sell the tuners too, I don't know. You'd have to contact him and ask.
I don't think Michael is...yet, but might. I think he's very busy with his Dresden model these days.
You can also go with the figure eight and pegs, Stauffer did, and it gives a nice balance to the guitar. There were a number of Stauffer style Viennese guitars (I think Stauffer may have made some like that too) with the three to a side tuners (I have one in my collection that's not by Stauffer but a contemporary) so that's another option.
