If you are in the market for an $800 treadmill, this is one to consider. The problem is that in this range you will probably need to use customer service and that could prove problematic.
Serious runners and vigorous fitness freaks would do well to give the NordicTrack T6.3 a wide miss, saving their money for higher models $1,500 and above. Great looking machine that doesn't need any introduction. The Nordictrack name doesn't need any introduction but you will pray that you never heard of them if you have a need for their customer service.
