screw ALL of the direct drive bench style saws. Get an old belt-drive contractor saw. Not as 'portable', but still easy for one guy to load in the truck....
Just depends on how portable you need to be.
Back when I did trim and set cabinets in track houses I was in a different house every day (sometimes two).
Those little 8" portables with a built in router fence are the ONLY option for that kind of work IMO. Especially if you plan on making any money.
A big custom or commercial job where I was going to be there for awhile,,, then yea, I'd bring in a big saw but not for production work.
