This is something I have been seeing on Ebay for awhile and don't understand what is going on. I am seeing multiple sellers all selling the same item - not the same model, the exact same item. Right now on Ebay there are four different (or are they?) sellers selling the same QDS-1. Note that the volume knob is not original and makes it easy to see they are all selling the same item.
