Jay,
I think that the Edition I posted on Half.com is the newest, 2003 edition as you mentioned. They list it as "Nov 2002" ... but it wouldn't make sense to publish a version in Nov 2002 then another in Jan of 2003 ... I think half.com has mislabeled it.
In any case, the buyer I purchased it from "booksxpress" shipped it immediatly, and it got here in under a week. What an incredible bargain, and it looks like they have more listed too.
I love getting a good deal
Jason
