If I had sounded like a Festool salesman, I would have recommended the Kapex for carpentry and job site work.
How did I know one does not need a Kapex to do carpentry? Because I have seen good work done in homes (including mine) by trade people using anything but the Kapex. Good work done using Dewalt, Makita, Ridigd, etc. etc.
By the way, I did not say you can't use a Kapex for job site work...in fact, many trade people in the EU do.
