David,
I had my frame shop save the design / layout so he could reproduce the frame in case I want to add more - or if anyone else wants to buy one.
It cost me around $300 - if they ship, I'm assuming you'd have to pay to have it crated up and sent off, but that gives you a ballpark in case you want to buy one.
Here is their info if anyone is interested.
