I've had a 40-694 for 2 weeks now. This table on saw is huge, makes for a lot of area to support a project. It seems to operate with very little vibration, with one exception. When the speed is set in the 3-5 range it starts to make some sort of a speed related harmonic noise. I guess it doesn't really vibrate more but, there is some increased noise. Maybe someone here has an idea as to what might be the cause. This saw also cut more aggressively than my old craftsman. I may look into correcting the problem like other people have with the Dewalt 788. One more thing, the bottom blade clamp is bending the blade towards the cutting edge of the blade. If someone has a fix for this I would love to here it. All in all I really like this saw it is a huge improvement over the old craftsman 16". Once the few issues are resolved this will be an awesome upper end entry level saw.
