Overanalyze - I'm not sure you're asking the right question. The answer is quite simply, yes, the bevel is very easy to set on the Kapex as already stated. If you have good eyes, it's only slightly more difficult than setting the miter. And if you don't have good eyes, well, it's a fairly large bevel guage for what it's worth. Justin brought up some really good points. It's a change in workflow and dealing with larger moldings, you'll find yourself cutting on the flat more frequently than not. Most people are set in their ways, so if you have a Kapex and a couple dewalts circulating among the crew, this might cause a small mutiny.
I'm just a hobbiest and I've struggled with this coming from a Dewalt 780. It's definitely got the capacity, and while light for a 12" saw, it's still heavy to cart to my work area and in some situations can create quite a bit of dust even with an extractor. The bevel adjustment is less than elegant (the norm), but seldom gets used because everything is cut standing up. There is plenty of slop in the head as well, so technique is important if you want consistent results. I wish I could offer more in the way of the Kapex, but as it stands I'm having a hard time carving out a block of time to go play. It's still in the box. In my case, I'm never really working on the clock, so speed isn't the issue. It's just adjusting to a change in workflow from what I'm used to. One thing is for certain, there are less brain cells involved for me when cutting upright.
