The Dewalt fence is more than adequate on todays saws. The Rigid not so much, Bosch make a 10” jobsite saw that’s also a pretty decent saw , fence and stand combo.
For a beginner I’d say either one DeWalt or Bosch would be better than a older contractors saw, I’ve owned a couple of 70 and then 80’s contractors saws , both where junk. Even a Sears 10” saw IIRC, back in those days there where NOT the jobsite saws we have today.
I have a old ten inch Makita that I really like when I have to take a saw onsite, it’s light weight , fits in the truck with all the other stuff a guy needs to install cabinets.
But for what the OP’er is looking for I’d recommend the Bosch or DeWalt to get started, if he ends up banging out of the hobby he’ll be able to sell the saw easily , IF he doesn’t trash it , leave it out in the rain , drop it etc.
On our jobs we have both type of saws they see heavy use , run good thin kerf blades on them and they are hard to beat , far better than the original 10” saw I brought in 1974 or 75 , a big brand name , IIRC a Porter Cable , it was junk , kind of looked like a Concractors saw or the time , but it was junk. Sold it or gave it away when I joined the navy , maybe my then brother in law ended up with it ???? Good riddance!
After that in the , in 1981 or so , just out of the USN with no credit Sears was the way back into wood working / carpentry.
Another contractors style saw, better than the Porta Cable , but still way less saw than the current job site saws IMO.
In 1985 ish I got a Grizzly cabinet saw with the Biesmeyer 52” fence , been a great saw. It’s not a Powermatic , but it’s close and at the time less than 1/2 the costs.
Ive worked in cabinet shops with Uni Fences , and IMO a Uni Fence is a waste of money , you can’t easily build jigs to use with the Uni fence , like you can a Beisemeyer.
