Quite a few years ago I bought a Precor 9.1 for $1500 and have never
been sorry. I know they don't have this model anymore, as I said, it
was years ago. Treadmills have a weight limit that you might want to
check on. the limit on my Precor is 250 lbs. Be sure to buy from a
reputable place that has a long business history.
I live in a brutal weather area so a treadmill in the basement is a
blessing.
