I hear ya.
The best selling one in the country is the proform 7000. After doing some research it's looking pretty good.
All the reviews I've seen are positive.(fishn4cuda is one of dozens I've read)
At 111" a.f.f., my ceiling height concerns me with two 52" cars. Seems they'll
just fit.
My concern is how do I keep the top car from hitting the ceiling without riding up with it each time
That'd be fun for a while, but it'd get old
