Stock Drive products (SDP/SI) now have a web site with online sales and sell lots of different types of pulleys and belts. Open ended as well. I like belts as they are very forgiving but you still need to keep the crap out. Just make sure the belts are lower than the table with a cover over them from direct spatter.
Unfortunately McMaster Carr do not sell to overseas people unless it is a big order. They changed about 2 years ago as the paper work was too much for them.

I am not completely useless.......I can always serve as a BAD example.
