My ideal would be to never have a speck of dust reach the gears of my table saw trunnion and that all sawdust would be sucked away from the saw blade and out of the machine as soon as it was made. I would never need to clean out sawdust from inside the saw cabinet and the trunnion would always operate smoothly and easily. While I don't expect to ever see my dream fully realized, there are saws on the market today that closely approach this level of efficiency in sawdust extraction.
One table saw manufacturer I know believes in "aging" its cast iron machine table tops before milling them flat. The tops are cast and then left outside in a "bone yard" to bend, bow, warp and twist in the sun and rain for a year or so. Then, they are brought inside where all the rust is removed and the table top is ground absolutely flat and polished to sheen. The theory is that the metal needs to settle into a place where all post-casting movement has ceased and that the table should not be ground flat before this is done. Otherwise, the table may move out of absolute flatness after it is part of your new table saw and that it not at all desirable. Why? Because the flatness of your table saw top will determine the accuracy of your cuts. Be sure to check your new table saw for table flatness with a straightedge on or before delivery and afterwards from time to time. Lay the rule across the table top at all angles and check for daylight under the rule or rocking of the straightedge on the table top.
Motor horsepower and blade size are closely related. The larger the blade, the more horsepower you will need to cut, at full blade height, through a piece of wood. Too much power is never a problem. Too little power can cause the saw to bind, slow down and even stop in the middle of a cut. This is not good, nor is it safe.
The saw should come with a Biesemeyer or similar type fence included in the purchase price. This type of fence locks and aligns itself to a rectangular tube attached to the front of the saw table when you press down on a handle. Fence accuracy and ease of operation will be important every time you touch your table saw and so a cheap fence is no bargain. The fence will probably read measurements along a stick-on measuring tape on the top of the front fence rail tube. You will need to carefully adjust the fence for accuracy. Instructions of how to do this should come with the set-up instructions for the saw.
Some of the nicer table saws have the caster wheels permanently mounted inside the cabinet so they are never seen and are never in the way. A foot pedal controls raising the saw up into the mobility position and then lowering it back down onto the floor. If your table saw does not have this feature, after-market mobility bases can be purchased as needed.
