We are not talking about renovation contractors or trade persons here who go to jobsites with a boatload of tools like mitre saws, jobsite table saws, track saws, sanders, etc. These are mostly tile installers or handymen who take on themselves to finish small trim jobs for bathrooms, kitchens, windows, decks, etc.
I know a retired carpenter who still does small jobs, but he earned his pre-retirement living using circular saws (cordless and corded) for decades. He is not going to get a track saw as a handyman, is he?
The point is that many people make a living as trade people (at least in my city) using tools that are main-stream and pretty basic. Some of them really can't afford using high-end tools with their limited budgets.
I don't know personally anyone who owns a Kapex to do site work, but we seem to find a good share of them here in this Forum. Dewalt, Hitachi and Bosch mitre saws are saws used by renovation and roofing contractors as far as I have seen.
