The Star Trac seems like a pretty good deal and obviously a lot more treadmill then the F80. I could get the Star Trac with a 3 year warranty for the same price as the S77. They will deliver, assemble, and haul away my old treadmill that bit the dust for $250. I would probably pay the $249 for the Sole to be delivered and assembled in the basement. Any one with success or horror stories purchasing a refurbished treadmill like this?
