Alfredo; If you haven't already bought the tablesaw, buy a good quality brand name circular saw first!
-it's really portable
-with a square and cutting guide/rail, you can do most of the wood cutting involved
-with a really good blade, reserved for the purpose, you can even do cabinetry.
Doing renos you'll use your circular saw more than any other power tool.
My personal choice...always has been...is an 8" rather than a 71/4".
If you're cutting 5/8" or 3/4" plywood, the speed (production) of the circular saw is untouchable by any other power tool (including setup time).
