I agree. Any type of shear (even handheld tinsnips) have worked better
for me than most saws. A fine toothed carbide blade in a circular saw
will make the better cut (square perfectly clean edge) but is not
worth the noise and dust. Strangely enough the glass fibers don't seem
to dull the blades of shears too badly.
As someone already mentioned you get a better egde by aligning the
blades closer together than you would for sheetmetal.

Finally, I bought the $79 8" sheet metal shear from Grizzly -- 100's of PCBs later, it still cuts like a knife through butter, and board edges are surprisingly clean and straight.
