This is a workout only a masochist could love! Buy the s5.6 or the s7.8 if you like this machine's feel.
This is an enhanced version of the s5.6. It's not a bad unit either if you like an excruciatingly painful workout. Freemotion decided to get medieval when they created this workout. I've often wondered if the engineers that conceived the design of this machine liked to torture small animals during their spare time. Normally we don't like to comment on the effect of the workout, just the durability of the machine, but this time I thought it might be good to warn consumers. The s5.8 is the next in the Freemotion lineup of striders/ellipticals. They packed the unit with more features and programming and put an extra $500 on the price tag as well. We would go with the s5.6 if you are looking to experiment with a new stride motion or just go for the gusto and buy the s7.8. If you care about the money you can't afford it anyway.
