I am sure this has been asked before, but if I search for "buying parts" every other thread comes up as a result for mentioning "buying parts". Not surprising I guess. In any case, I need to buy some parts for my Genesis EP-320. Is there somewhere I should go for the best prices? I have been to Weber, appliancefactoryparts.com, and ereplacementparts.com. They were the only three I found that sells frame parts. Interesting that parts directly from Weber are less expensive than the two "discount" sites. Thanks.
