I know they're rare, but if anyone can offer for sale I'd be interested. I am actually looking for four total. Or, If anyone has the skills and is willing to build them for me please contact me. I believe plans can be found for them on several forums right here. To be honest, I don't know what a fair price for a used pair or to have them built is. But, I'm very interest to know. Please contact me if you can help me or know of someone who can.
Best Regards,
Aaron
