Very cool bass for sale.

I think you're right, that's a very cool bass. I would love to get my hands on one of those. I've seen a few on here and they look like really special instruments. When you think it's overpriced, do you mean in terms of its actual worth as a high-end instrument or its worth in a market currently infatuated with old Fenders for some reason? I would take one of those over three same year Fenders on the blink of an eye.
 
Cool Bass.
The price seems fine to me. It's a rare, vintage handmade (North American?) instrument for only $900 USD. If you like it I'd snap it up. In a world where Peavey T-40's are getting into the $600 range, a bass like this isn't likely to get any cheaper.
