p99auctions, if you need, you can feel free to grab any of the log data sent to ahungry via this log file (refreshes automatically):
http://ahungry.com/eqlog.txt.bz2
It's generated every minute, and contains the latest 2MB worth of log data compressed (so its only about 250KB to download) - at the moment it contains around 13,000 of the latest unique auctions (data from 12/27 to today).
