I was on the phone with David from bulleye today and asked him about the chargers that the Ebay seller you listed is selling and he said that they are not BullsEye chargers at all. Neither BW or Bullseye makes an S376 with ETT - so that is flat out wrong; and he said the S378 is no longer made and that is likely wrong as well. He also mentioned that those are off the shelf covers, not Bullseye's race covers. I would not take the chance of being scammed by that EBay seller.
