Welcome! Assuming you're looking at the stationary PCB270TS and Ridgid R4512 (made by Dayton)? The Craftsman 21833 is essentially the same saw as the R4512, so check into that one too.
The Steel City 35990C adds cast iron wings to the mix for around the same price as those mentioned.
The Craftsman 22116 hybrid (made by Steel City/Orion) goes on sale in the $700 range occasionally...it's a bit more money, but it offers big yoke style cabinet mounted trunnions, a full enclosure, granite top, more mass, and a good steel t-square type fence.
The Grizzly G0715P hybrid is getting good marks as well...full enclosure, solid cast iron wings, excellent Biese style fence. ( ~ $765 plus s/h unless you live near a showroom).
A good used saw is always an option if you stumble into the right deal. If you've got 220v, a 3hp cabinet saw would last you a few lifetimes and make easy work of anything you'll encounter.
The key to the end performance of any of them is good alignment and good blade choice. Good luck and please keep us posted!
