"IMPORTANT"
When buying used treadmills from places like Craig's List; my advice
is "don't buy
it"... unless it has been inspected by someone who
knows if it worth what you are about to pay.
Sometimes what seems like a great deal can end up
costing you more than if you would have just bought
a new treadmill in the first place.
I have heard
every excuse as to why someone has sold their
machine to an unsuspecting buyer; truth is, most
times it is being sold because it is
BROKEN!
And, the
person you are about to buy or bought from has
already looked into getting it fixed and found it is
better if you bought theirs to subsidized their
"new" purchase.

Also...
never pay any more than 35% of the machines
original value up to 3 years old (there are
exceptions). You can do a
little research on-line to find out what the
treadmill is worth. If the treadmill is over 3 years
old don't pay more than 20% of the machines original
value.
It may be worth the diagnostic
fee to see if any used treadmill is worth
buying. If I approve the treadmill as a worthy
purchase, I will give you a one year warranty on the
labor costs; that could be as much as a $185
savings.
