Lots of people still shop on eBay even if you don't. So that maybe explains why it is discussed.
As to why the drum is priced so highly, that could be answered by the seller. A simple message might help. Who knows, maybe the seller could sell it for less to you. When I sell such items on eBay I always put a "Best Offer" option on there. Anyway, I can't do much for you in terms of that seller, other than to suggest to you that you contact him/her and attempt to find out directly instead of trying to start a moaning party.
