The first decision you will have to make when you buy the best table saw is to find the balance between accuracy/power and mobility. If you are someone who requires your saw to be moved around to different places like yard, garage and different houses, the saw you pick will look quite different than what a woodworker who is cutting large plywood sheets will require.
The table saws normally come with basic setups; portable hybrid, portable, and stationary:
Benchtop/portable
They are the saws which are both quite small and are normally the cheapest of the categories. The saws are normally built so that those using them can pick them up literally and carry them to where they are required.
The negativity of having a model which is portable is that, they are known to be quite limited in terms of sizes of the wood that you are going to utilize. Most of the time the tables are usually very small, and it is not safe cutting large wooden piece on them. Another negative with the saws is that, they are not sturdy as some of the large units will find. It can end up affecting accuracy if you are out looking for cuts which are precise.
There are a variety of plans available online, showing you the way you can build a large table which has bigger cuts, but they will not improve performance significantly as well as the accuracy.
