Well Adrian, you have to take into account that Aaron is well known and has a good reputation so people will pay what he asks for on his items. I remember about 1 year ago Aaron was selling a 3rd print
POTVQ and wanted 800+ for it. UMmmm look on ebay and see how much a 1st or 2nd print sells for, around 300+. Aaron is somehow able to demand a price and people are willing to pay whatever to get certain items. If Aaron sold a A1-4 module for $100 would the estimate of the item then be $100? I THINK NOT. I stick behind my guess on the Series I and II items though I wouldn't be surprised if the Series II costs more as it is much harder to find.
