I was talking with Tim at Performance today, he is selling (for a friend) a Panther Folding Tandem:

"My Friend Eli has entrusted me with selling his tandem recumbent.  Manufacturer is Recumbents by S&B. According to his website, it is a Panther Tandem. Calling it the folding version....it comes apart for easy transport. He is selling it because his bride likes the other tandem better.  
Deore deraileurs, barend shifters, and I have to tell you it is a hoot to ride.  If you know anybody who might be interested send it to them.  I have the original invoice at $2800.  Eli would like to get around $800 for the bike.  Currently it is at my house in McKinney and is ready to demo.  Current wear and tear has been my oldest daugher and I running up to Sonic.  Laughing the whole way.

BTW, when I went to the Pacbell.net website, Norton gave me a "Site is unsafe" message, the PBA link is ok.
