I too had the opportunity to play around with a Kapex recently..... I must say that I am impressed!! Right now, I am using a Makita LS1214 12" SCMS, which by the way was just ranked #1 by Fine Homebuilding, so that's the benchmark I am comparing the Kapex to. The things I am most excited about the Kapex are:
1. Finally, a LARGE bevel scale where you can pretty easily adjust to within around a 1/4 degree or so, which would make cutting really tall baseboard much easier on the flat.
2. The Bevel adjustment knob looks nice. It's been done before (Hitachi C12LSH), but the Kapex version is much more ergonomic.
3. The deep throat behind the arbor is a really nice feature. Again, it's been done before (DeWalt).
4. Ability to bevel past 45 degrees, something my Makita won't do.
5. Dust collection. I haven't actually seen it, but I've heard dust collection is nearly 90%, which is basically unheard of for a SCMS!!
6. The V-groove at either end of the table make for a VERY handy point for which to mount aftermarket accessories..... I've already seen one clever manufacturer take advantage of this!
Things I'm not impressed by:
1. The angle finder looks nice, but it's certainly nothing new. In fact, when I was playing around with the saw I found that, with the angle finder stored on the saw, it limited the maximum miter range of the saw..... Is this just my perception? What do current Kapex owners say?
2. The laser seems nice, but if I had to chose between a light (like on the Makita) and a laser, I'd chose the light. I work primarily on-site, and so I don't get the kind of great lighting you'd find in a well-equipped shop, and I don't really like staring into a halogen lamp all day either. I know it seems hokey, but that little snake light mounted on the Makita is VERY handy!
3. The 45lb weight sounds nice, but my Makita 12" SCMS weighs a mere 52lbs, so I won't be shedding a lot of weight.
So, from my brief (around 15 minutes) session with the Kapex, here are my two cents: The Kapex appears to be a great saw that takes many great features already existing in other saws, and combines them into one very well designed unit with a few extra tricks up it's sleeve. Is it worth $1300 to me to get these features, or am I better off waiting for Makita and Bosch to release their next generation saws, which MIGHT be every bit the saw the Kapex is for half the price? Or, even if they're not quite the same as the Kapex, maybe they'll include many of the features? I'm not sure yet..... oh well, at least I have several months to waffle!!
Edit: I imagine that between now and July the sticker shock will have a chance to fade.... besides, it'll be nearly impossible to resist when Festool starts releasing their snazzy videos for the Kapex! ;D
