Finding Cog belts and pulleys ?

In your motor driving systems have you ever come across used pulleys and low cost cog or v belts ?

Typically I get all of this stuff from McMaster. I cannot say it is particularly cheap, but it is convienient.

I would imagine that a used automotive surplus store or junk yard would provide good deals (if you don't mind used or 'new old stock').
