One of the more useful add-ons for just about any table saw is either an upgraded system offered by the manufacturer, or an aftermarket miter gauge or crosscutting sled. These tools provide, in various combinations, repeatable incremental angle positioning, longer fences, stop blocks and other advanced features that can come in handy in projects that call for precision crosscutting.
Beginning at the bottom, the table saw base houses the working parts of the saw, including the trunnions, the arbor assembly, the sector gears, and sometimes the motor. On some saws, the base is a "cabinet" type, meaning that a fully enclosed base extends all the way to the floor. Other saws have an open base, meaning that the base consists of a metal box that surrounds the internal working parts of the saw on four sides, but not the bottom. Open base saws have legs that extend downward from the bottom of the base to the floor.
Most table saws - other than small bench top models - are equipped with induction type motors in the 1 - 5 HP range. On larger saws, you'll most often find a "totally enclosed, fan cooled" (TEFC) induction motor. A TEFC motor is designed for continuous duty and is sealed against dust and other contaminants - a significant advantage in a woodshop.
The quality and accuracy of fence systems, however, varies greatly across the spectrum. The quality of a table saw's fence system is an extremely important consideration: A poorly designed or inaccurate fence greatly diminishes the quality and accuracy of the cut, and can be a source of significant frustration. For saws in the price range of most hobbyists, the famous Biesemeyer T-square fence design sets the standard. Fortunately, many smaller, more affordable saws come standard with a reasonably accurate system patterned after the tried and true Biesemeyer design.
The smallest motor I would even consider for a 10-inch saw would be 3 horsepower. For a 12" to 14" saw it would be 5HP and for a 14" to 16" saw, I'd like 7.5 HP. You will also need to consider if the saw motor is single or three phase. Three phase motors use electricity a bit more efficiently. If you don't have three phase power at your location, however, you will either have to buy single phase or purchase and install a phase converter large enough for your saw motor. Most saw motors use 230 or 460 VAC power, so make sure you have available in your shop the voltage your saw will require. Three phase motors can run on 208 to 220 volts or higher, depending on the motor.
