I just talked to my quest guy and he is adament that this orbit has nothing to do with quest or any other label that he has ever carried.
My theory on the labs that are coming in with the really low prices, and this in only a theory, is that they do not have a real chemist making the gear. The reason why I think that is that in any UG lab you have a chain of people, there is the guy(s) that own the lab, the chemist making the stuff, and the rep selling it. So if you are dealing with a direct rep, then there are minimum 3 people that need to get paid. When you factor in the cost of the raw materials, lab equipment, glass bottles, etc, with those 3 people, then there is a minimum that has to be charged for those 3 to make any coin. When a "lab" comes in with prices way lower than that, then someone is missing out of this chain, which odds are is the real chemist with the knowlege to do it correctly.
