Ayup. And they say $150 up front cost (if installed on the assembly line) and a
$75 cartridge replacement cost, but say nothing of the strain on the arbor and
trunnions when the assembly instantly drops below the table and is jammed to a
stop.

Think about what you're saying here. IF it works, I'm wondering if I
ran my fingers into the blade and it snapped my arbor and trunnions -
destroyed my saw - but didn't leave me fingerless, would I feel I'd
rather have lost my fingers (or arm or...) than the saw? I don't know
of any piece of machinery anywhere that I'd trade for any body part.
