There are several SUN EZ Tandems out there on Craigslist. We really like ours wich we've had about three years with no problems. At one time we rode a Ryan Duplex (now Longbikes makes the same tandem = Gulfstream) with the under seat steering. As the Capt. I like the EZ way better. Seats are way more comfortable as well. EZ's go for around a thousand bucks now days as well.
I haven't see a Bike E tandem in ages.
