My Bowflex Xtreme arrived last week. I got it assembled and it is pretty great.
The power rod resistance feels really great and I can do all sorts of weight lifting exercises with it (and I don't need a spotter). Having it in my basement removes the "I don't feel like driving somewhere to go exercise" excuse too.
... While the order process wasn't the best (I didn't get updated on the order status, and I didn't get a UPS tracking number via email until the day before the packages arrived), and UPS managed to mangle one of the boxes (nothing was damaged), I still highly recommend the machine.
