I am a very happy owner of the Proform 705. I chose this model as it was in the price bracket I wished to remain in. It took about 2 hours to build as I wanted to make sure it was put together solidly. Manual in my opinion was excellent (I am rather practical though.) The Proform is a well manufactured and smooth treadmill. I use it most evenings for around 15-20 minutes. One and only negative of the machine, is that the handle bars are quite low down, and difficult to hold on to sometimes. If these were adjustable or higher up on the machine, that would be much more comfortable! I don't usually recommend products but I would and have done with this treadmill. Definitely good value for money.
