I had a 20" DeWalt 788-- it was OK - did not stand up as I thought that it should. Previously had owned a couple of Dremels-- one hand been the "Tin Man" 2-3/4 inch blade job. Both had stood up very well. The 2 speed was sold because of a 1500+ mile move; should NOT have- was a very good saw when sold.
The DW was bought new in OR and the only really better thing about it was the 20'" throat. When it gave up; I bought a 18" Porter-Cable -- seems as durable as the DW; although, I have not worked it quite as hard. I have not cut as much hickory with it.
The 18" is way to small when I start making rockers. Both the Dremels used pin end blades and would let me turn them 90 degrees; made the rockers very do-able on a smaller saw. I would love to find a reasonable priced 20" saw with the 90 degree blade feature. It would be able to cover all of my needs.
The P-C has a much better light then the DW HAD. Better blade clamps and a vacuum port too. The DW did run smoother though. The cutting capacity seems about equal and both seem to have had about the same power. My 788 was a type II and I heard the type I is a better saw. I have debated trying to get the DW repaired at that $250 max- thing. The P-C was less than that new with a 3 year extended (even normal wear allegedly covered) warranty. I might modify (I have looked it over and it is a possible thing to do) the the P-C take pin end blades sideways just for the rocker cutting.
I will probably (I HOPE) be in the market for a new saw in about 3 years.
If I do ever get a new saw again;t will probably be a 20" or larger.
If anyone wants to ask me about any of them, please do, I will happily answer.
