This last weekend I went on the Omaha "Corporate Cycle Challenge" and noticed at the start there was a couple that had a Tricycle Recumbent - it was pretty cool and neat which got me to thinking about one and that would allow my wife to stay with me instead of me leaving her in the dust - plus it would give her more comfort on a tricycle.

Questions:
1) What kind of price are these things?
2) What about used price?
3) Where can I find them? Used and New...
4) For the tandem part - when one is pedaling, I'm assuming that the other crank is going too - so if I'm wanting to do 100 cadence, then my wife would be too...
