I originally bought a left blade saw to see the cut better, but it does throw up a lot of crap. If you want precision, clamp a straight-edge to the material and run the circular saw against it. Much better than visually watching the blade.

It can be helpful to have both. When cutting mitered stair skirtboards, it is a lot easier having a left and right circular saw on hand.

The pictured Porter Cable is a nice saw. I have the left blade version.
