I was looking at foldup treadmills but they're too long (I don't have space available for a 55 inch belt. The Bowflex TreadClimer TC5 isn't a foldup but it's only 3 1/2 feet long and just over 2 feet wide. The ads and commercials tout it's multi-faceted approach to exercise but before I spend $1,000, plus shipping, I thought I should get some feedback. So... would you recommend the Bowflex Treadclimber TC5 or... something else? Thanks so much!
