My DW is about 4-1/2 years of relatively hard use. Made many hickory flooring nameplates! That will test a saw!
I hated the lamp from day one-- I have made adaptors and use an actual spring arm desk lamp! Then I found the wonderful led now at Rockler for $50!--Has GLASS magnifier built in! GREAT LIGHT!
The blade clamps are not great; but, I even looked at the Excaliber and those are a little better, not a bunch!
I have no experience on a bigger Delta, but 2 of my sons have 16" ones and I did not like either of the 2--Sorry do not know model #'s.
They might be great saws too, I just did not like how they felt and ran! I had used an old Dremel for several years and actually liked it better than the Deltas. The DW is in my opinion a better saw for me than any of the 3 perviously mentioned ones. I would buy another DW #788 at this time. But, I would see if I could test drive a few comparable ones just to see what fits me best!
Do what fits for you, not for anyone else! Please the person in the mirror!
