In short. What's wrong with the delta and craftsman pro and why buy the bosch
or dewalt?

Well, I JUST bought the Dewalt 12", double compound, non-sliding.
Couldn't justify the extra $250 for the sliding feature. I bought
Dewalt because I haven't had 1 complaint about any Dewalt tools. I
DID have my speed control on my router go bad, but there's also a
service center within 10 miles of my work, and they had a great turn
around time, and Dewalt even warrantied the work even though it was 2
months out of warranty.

I'm VERY happy with it. The first thing I made was a miter work
station, with 3' extensions on each side of the saw, as well as a sort
of box around the back of the saw that is hooked to my dust
collection. After playing with it for a while, I decided that I
didn't even need to hook the saw up directly to the DC hose, as the DC
port on the saw is in the back, and just shoot the dust into the open
DC port.

It was a breeze using the miter saw in conjuction with the table
saw. They sure complement each other very well.

The accuracy of this saw was right on out of the box. No adjustments
necessary.
