As Leo G has said, you reach a point in price where the difference is more for increased production than for accuracy. If your tools are smooth and accurate you can produce work that is high quality.
Sometimes, material handling is just as important to accuracy as the actual tool, and this is where a large table surround on your table saw is necessary. It also adds immensely to the safe operation of the saw. You can't make accurate cuts if your work is slipping around and you are trying to hold on to it on at the same time. A good outfeed table was one of the last things I made for my saw and it's been one of the best things I ever did.
My tablesaw setup is a bit unique having 3 saws all linked together. Others here have made 2 saw setups or large surrounds, but I had a chance to buy a 3rd saw on Craigs List to match the other 2 saws I already own, so it was a "no brainer". It was another of the best things I have done to add convenience and safety to my shop. No more changing saw blades or swapping out dado sets for me.
They are 12" Craftsman motorized saws, no longer in production, so I jumped on that one. Again, nothing fancy or high end price wise, and the setup works very well and is very accurate.
When I need to bring a saw to a job site, my Bosch 4000-09 is one of the best. Lots of power and a decent fence that locks parallel to the miter slots. It cost around $500.00 new, so not too bad. I had to help a buddy who bought an older house reshingle the front wall where he had installed a new window and door. The siding was Red Cedar shingles in various widths which had come off the inside wall of the porch. His table saw was a El Cheapo, Craftsman 10", noisy, lousy fence, and no miter gauge. So... I ended up ripping the shingles off the existing straight edge to make them parallel. Some I had to "free hand" because there was no straight edge.... a bit scary, but very workable since they were only 3/8" thick at most.
After I tightened the adjustment on the fence it would stay locked pretty much parallel to the miter slots. It made me so appreciate my good Bosch!
