Starting at the bottom of the price spectrum:
Job Site/portable $500.00 or more
Contractor ......... $600.00 or more
Hybrid ............... $800.00 or more
Cabinet ...............$1500.00 or more
Sliding table ........$5,000.00 or more
There's another type, mostly used for cutting sheet goods, a vertical panel saw depending on whether it is a 2 axis it may cost $7,000.00 or double that.
Used prices vary all over the place. My buddy who makes custom doors, got a $15,000 Holzher for $500.00 by being in the right place at precisely the right time. I was there with him to load it up, so I know what it was. I was so envious that I made a 2 axis panels saw for myself from a RAS carriage. It's not a 15K Holzher, but it does work well.
Panel saws reduce the handling issues of large heavy sheets to a great extent, but most woodworkers just make large surrounds for their table saws. Good work support is an important safety feature and should be part of every woodworkers mind set and just as much as picking out the proper table saw.
Fences are THE most used table saw accessory and should be rigid, accurate and self aligning..... Biesemeyer or their clones work very well. Since I own one of each type, I can say with some certainty that you can do good work with any type of saw IF you have it set up properly and the saw will maintain that setting. Power and blade type also are important aspects of selecting a saw. If your thickest cut will be 1 1/2" or less, a 1 HP induction motor will be adequate.
If you're cutting hardwood and 1 1/2" or more, you'll need 2 HP or more.
Dust collection varies all over the place also. Contractor saw made before 1990 have lousy DC. A blade shroud that wraps around the spinning blade does wonders for dust collection. Look for that on any saw you are considering. I fabricated a sheet metal shroud for an older Powermatic 12" cabinet saw and that made a big improvement.
