L'esc - excuse my curiosity, but why a recumbent? Someone mentioned keeping weight off knees and ankles, but if you need to press with force X to turn the pedals at a given rate/resistance, it doesn't matter whether you're sitting upright or lying down - there will still be force X going through your legs. A recumbent would also take up more floor space, and there doesn't seem to be as much choice.
However I can see that it might just be more comfortable, if that's what you're after.
