Now, most of the "reps" you are referring to are just resellers. they get a discount on a product, mark it up a little, and resell it. That is not a rep by any means. Manufacturers reps work for the company and are not typically involved in direct to consumer sales like that. A real rep knows their product because they work for the people who make it. Resellers just jump ship to whoever can get them the most margin, or in some cases even sign them on at all.
