The cabinet saw, contractor saw, hybrid saw, and bench top saw are all types of table saws that will help you in your woodworking projects. Each saw is slightly different to accommodate the certain needs of the woodworker. One must find what they need out of there table saw before determining what type of model they need. However, for the average woodworking projects, you cannot go wrong with a quality contractor saw.
The bench top model is preferred for those who are looking for a table saw that is portable and less expensive; however, remember that you always get what you pay for. The bench top saw has the least amount of capability out of any of the table saws. With the decreased size and weight of the saw, it is less durable and there are greater restrictions of the size of projects one can do.
There are many things you will want to consider before purchasing a new table saw for your shop. There are three main types of table saws: (1) the lightweight, inexpensive and portable contractor's saw, (2) the cabinet saw, so-named because it has an enclosed cabinet as opposed to open base and (3) the new breed of so-called "Hybrid" table saws which fill the price gap between contractor's saws and cabinet saws. This discussion will be only concern cabinet saws because, in my experience, nothing less will do for a shop that produces fine woodworking. Smaller saws lack both the accuracy and capacity of cabinet saws.
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.
The trunnion is the mechanism inside the cabinet which is responsible for both raising and lowering the blade and tilting the blade for bevel cuts. It is controlled from the outside of the saw by two separate wheels or cranks: one for raising and lowering the blade (usually found on the front of the cabinet) and the other for tilting the blade (either left or right, depending on the saw) which is usually, but not always, located on the side of the cabinet.
