Where do you buy your parts?
I'm taking a class on bike maintenance and repair. So, far it has been a great class taught by a very knowledgable person. But, with this knowledge comes a question: Where do I buy parts?
I don't want to cut my LBS out completely. But, for many things there is a pleasure in doing it myself. So, for things like cable, cable housings, screws, wire, gears, etc. Where have you found to be the best?
(I've seen some ads and gotten some mailorder catalogs that are not only truely expensive but are questionable. Obviously geared to those with more money than sense, not me).
