Is it this one? http://cgi.ebay.com/Terry-Trilogy-sm...QQcmdZViewItem

If so I wouldn't bid on it. I think its too old, it only has a 6 spd freewheel and I don't like the Biopace crank. While elliptical rings are currently popular (I have them), Biopace got the orientation wrong, and they can cause knee pain. I think if you are patient a more modern bike, ideally 9spd will get listed.
