Smart counters company Sellathon, Inc. has created a list of the top ten thousand eBay sellers (by feedback) worldwide. The list shows whether sellers have an eBay Store, if they are PowerSellers, their country, joining date, and more. It also shows that a significant proportion of top sellers are no longer registered users (banned) on eBay. See the list here.

Nortica has been running a similar service since 2003.
