When I was in the business, ~10 years ago now, always preferred Makita saws and Hitachi nailers for the framing and form work. Makitas were simple and rugged, the Hitachis were sleek, light and fast. For reno/finishing had a Bosch table saw and Bosch/Porter Cable guns. Most were bought used. A lot of crews liked Bostich (cheap) or DeWalt (over rated).
Did buy a couple Paslodes when they first came out, really great guns for doing foundations, form work etc. Not great when they got wet however which was a problem here on the west coast. Not very cost effective if used on a regular basis which I did see some do. Also picked up a palm nailer, mainly because we had a young guy who wanted it and we liked him, so got it for nailing hangers. After he left, I don't think it ever left the truck again. I tried it once, seemed to be a novel solution looking for a problem, never saw the need for it personally.
Pawn shops carry a lot of handyman junk but do score professional construction tools occasionally, sometimes barely used...
