Many years ago, when all saws I used were Porter-Cable or the Skil wormy, I bought only those saws that had the blade on the left side. It helped me by making things consistent. I had to be certain that off-cuts were always to the left. Seems that I always went home covered in sawdust at the end of the day, too, due to the exhaust port being toward me. Now that I have the TS 55, and a couple of CTs, I go home a bunch of cleaner. It's very easy for me to use the TS with either hand, depending on circumstance. The biggest change is that the off-cuts are now to the right.
