I heard on here that the Dewalt 12" deflects the table when it is secured (mostly an issue on non preset angles). I went to HD and sure-enough, lock down the lever and the table lifts up 1/16" to 1/8". (have a look at the design and it's obvious why).
This Delta seems to have a lot of new "ideas". While that can be great, it can also lead to new problems. On paper, the front lock bevel is handy; built-in crown molding stops a plus; vertical motor interesting idea;
cost-wise, it's 400 less a 50 rebate; so the same as the Dewalt
