Recumbent Exercise Bicycles

Does anyone know where I can find reviews on exercise recumbent bikes? Or recommend one? I have been looking at the Edge 440 recumbent exercise bike, but cannot find any information on how good they are. I haven't heard of Edge before and wonder if anyone has anything made by them or where I might be able to go online to find any reviews on it. Also if someone has one that they would like to recommend. It is going to be a gift for my father who is approx 6'2" with long legs so the seat needs to be quite adjustable. Thanks
