True really stepped up to the plate last year to solidify the company as a leader in high quality home treadmills. If you are considering the ES7.0 pay the extra for the ES9.0.
A single top end model makes more sense to us in the True line. For the few extra features you get, pay the extra $500 (the decline feature alone is worth it). Some may ask why you would pay over $5k for a home machine and that's any easy one...if you get a treadmill as quiet as a True it makes all the sense in the world. Commercial machines can be noisy.
