Need opinions on ProForm treadmills

Hello

I had a ProForm 725 TL (or something similar) from around 1998 through 2001
that performed well and hadno problems.

I'm in the market for a treadmill but I am surprised, when I read the
newsgroups, to see that most people trash ProForm treadmills as being prone
to defects.

Has their quality deteriorated of late or is it that maybe what I look for
in a treadmill (2 hours walking every day) can be handled by a ProForm ?

Thanks for your opinions.
