Each of us has to decide how to spend our budget for tools.
By the time the Kapex was announced I had become a Festool convert. Over the previous 60 years I had owned many radial arm and miter saws. In fact I still had a wonderful 14" radial arm saw as well as a near-new miter saw with an accurate laser.
I value my time. My goal is to make very accurate cuts that do not require additional steps, especially to make them glue-ready. All the solid lumber I use is expensive. Before I even could pre-order a Kapex I had seen them demonstrated many times. I also had the chance to make cuts in material I brought with me to shows. I convinced myself that for my use the Kapex would become my primary sliding miter saw for finished work. I never planned to replace either my larger radial arm or smaller miter saw. In fact all three are installed in my shop along the same wall, sharing a common bench.
I do not use the Kapex to cut typical framing lumber, since my 14" radial arm saw is designed to do that. To reduce wear on the Kapex blade I use my smaller miter saw when the finish of the cut is less important.
For use on site, or closer to the assembly area of my shop, I bought a second Kapex.
For me the Kapex is worth the price.
