Whoa there! This bad boy runs around $4,000 for a commercial grade treadmill. The Lifefitness T5 will last you as it is meant for gym magnitude use. However, as for features, this really doesn't have a whole lot on the other Lifefitness models. I highly recommend looking at the T3 or F3 if you haven't already. The same motor, but a few more electronics and larger belt (60x22). Otherwise, there's nothing that stands out about this to make it cost so stinking much. Great machine, but beware: it's overpriced!
