If you want something lower profile than the LCX 425T, this is it but these are really intended more for the club than home use. It was equally impressive performance wise but the $2000 extra would make me opt for the lower end model.
Another strong model from Cybex which would appear to be more comfortable in a club. If you want a machine in your home that is about as good as you can get quality-wise, this is it. We still service their treadmills from the early 80's so these qualify for the longevity award.
