Great thread, thanks.
Started on a Hitachi, moved to and EX-21, and also picked up a DW 788 and a Hawk VS 21 and 26.
The Hawk has issues with power at slow speeds, as well as with blade changes and it is a bottom feeder, period. The DW needs Hercules to adjust the arm tension and the maximum lift of the arm barely accommodates a small stack. The tension adjustment and the blade clamps are very good.
The EX has decent blade clamps, but has a tendency to release the blade from the lower clamp, a feature not found on the DW 788. The over-center tensioning on the EX works, but is a very poor second to the DW 788. The EX has the tilting head which is a fabulous feature for those doing bowls because you are not fighting gravity as you make your cuts.
Dust collection is pretty easy with a box fan and a filter, no matter the saw.
Net of everything, the EX is close to perfect for my needs but needs a few tweaks and it would be great if General and/or Ray were reading this.
