I don't have a kapex- yet
but it's high on my list. From what little I know having used it briefly at the dealers, I would really like that digital readout. I have that on my Milwaukee saw now (12") its really nice, 1/10th deg readout. Problem is that this saw is a huge boat anchor! oh, it's got lights built into the head, so that's good.
Smoother "swing" on the table, anyone tried the new Makita? super smooth! Up front bevel controls? not sure about that, I rarely need the bevel feature, so that's not an issue for me.
Lasers! can't see them. red/green color blind issues, ya I'm defective so sue me! LOL I'm so used to not using them I don't know if one would be an advantage.
That shadow light that someone mentioned on the Dewalt? I've used a Dewalt with one on. It is a good sharp line, but it moves as you bring the saw head down close to the wood - sometimes that's a pain to do, three hands needed.
Re-design of the crown stops, if you use the festool stand, the stops can't go on.
Oh, and if business continues to be good, I'll need this new designed saw by mid October
