I'm a big RAS fan. I've had a number of CM saws. I have had 3 CM RAS's in my shop. All older (late 60's - 70's models) These were by far the better CM ones. I would replace one, after finding another one in better condition, and return the motor on the old one for $100 from Emerson.
Then I found a Red Star RAS, then a Dewalt. No more Craftsman RAS in the shop!
The CM saws are decent. The Red Star (Delta turret arm design) and Dewalt are much better.
If I didn't have a Red Star/Delta or Dewalt, I would not hesitate getting an older CM RAS, untill I found one of the others. You can always get $100 for the CM motor.
Dado's are a big reason I like the RAS. I had to cut 10 1" x 1 1/2" dados in a few 2x4's. Clamped them together. Cut each dado in 3 steps. All dados cut in under 5 minutes.
Never had a problem with blade lifting work off table. When the blade starts cutting it is pushing the wood down. As long as you are pulling to cut, rather than pushing.
The PO of my latest RAS is a cabinet maker, and told me to be sure to push to cut. (Wrong imho) Then again, he also told me to be sure not to tighten the arbor nut very much. Wrong! With a saw with blade brake, tighten the nut!
