That's one of the guitars on my list, too, and the best advice I can give you is just keep an eye out. I don't believe there were a lot of them made, and they're one of the rarer models that comes up for sale. There was one on eBay not long ago from Japan, so they do pop up every now and then.
You kill me. This did not show up in ebay Germany neither did my Google Alert work. I am looking since 6 months couldn‘t find one and now I miss this...
