Having sold a lot of items via Ebay, I feel for the seller. As he points out, he's not an expert. For someone in that position, the number and subtlety of Alembic options are a bit of a minefield. I have sold two Alembics. In both cases, I thanked my lucky stars that I was knowledgeable enough to field any reasonable question from an informed potential buyer. This is not to justify inaccurate representation, but it looks like the seller went the whole nine yards to correct the mistake and more.
On the other hand, many Ebay sellers don't appear to have done any homework before posting Alembics for sale. That does piss me off. I guess I respect anyone who makes a good effort, but lose patience with those who don't.
