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.
If you consider that a sheet of plywood measures 48" in width, I would think that you might want to opt for a 50-inch rip as opposed to the slightly less expensive 30" rip capacity. You might want to rip off only one inch from that sheet of plywood and, while doing that, you will want the plywood to be fully supported. You might want to crosscut a sheet of plywood into two 48" pieces. You also should consider the rip space to the left of the blade: The wider, the better. Sometimes, you might want to accomplish tasks that require the fence to be put over to the left side of the blade.
The trunnion determines the accuracy of your cuts so you want to be sure that it is well built and accurately machined. The saw blade must always be exactly where you need it to be. Furthermore, the trunnion must be easy to operate. It should not require Superman to raise or tilt the blade. As time goes on, you may find that it is harder to turn the wheels or cranks that operate the trunnion. This is usually because of sawdust contamination of the gears and/or lack of lubrication. Some better saws have ways of eliminating sawdust from the cabinet into an external dust port before it can get into the gears. Other saws come with self-cleaning gear teeth.
A table saw is the most common piece of large woodworking equipment found in shops around the world. Table saw are very versatile, and if you can only have one piece of woodworking equipment, a rigid table saw is probably the best one to choose. These more portable types of table saws offer versatility and ease of use with the convenience of portability.
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.
