I believe I read on here somewhere that you offer extended warranties, am I correct? Either way, my husband & I are looking at a Sole F80 treadmill that comes with a lifetime warranty on the frame, motor & deck, 5 yr. on electronics & parts, 2 yr. labor. I'm a bit confused...how are you able to buy an extended warranty on that kind of time frame? I don't want to be paying for a warranty while the manufacturer's is still valid. I know some warranty companies are a rip-off too. Do you have a list anywhere of those to stay away from? Thanks for your help!
