Cancelled the transaction. I called eBay again and they felt it was a bogus account set up to phish for banking info and advised I cancel. As the old saying goes, if it seems to good to be true it probably is. But I'll watch and see if they come back with a new listing! (And, like you, I did consider those scenarios, but it's far more likely it's a fraudulent listing, sadly).
I think you did the right thing. I would of done the same.
