super stuff,

I've seen the McMaster Carr belts (and bought a few) and the one SPI
has, but have not found a review of the different types, why one is
better than another.

this piqued my interest. Since I'm doing light duty XL belts are
fine and I have stayed with the lower cost variety because I just
don't know WHY I would need to get something better.

can anyboy shed some light on the reasons why one needs a high $$
belt ? or why one is noticably better than another ?
