So I want to start riding a bicycle for exercise, but I really hate traditional bikes because of the seating position. So I have decided to go with a recumbent. I know that I want one with under seat steering, but can't decide between a two wheeler or a trike. Also, I would like to find a good one (used is fine with me) that is not gonna break the bank. Most everything I have seen is well over $700, and even the used ones seem to retain their value quite well. Anybody have any ideas where I might be able to find some good inexpensive choices? Also, input from those with 2 and 3 wheel versions would be great.
