Diff tools

SourceGear just released an update to their free DiffMerge program. This product caught my eye because it has a 3-way merge. My current favorit Diff tool is Beyond Compare 2 from Scooter Software ($30). It has more features than DiffMerge, but doesn't include the 3-way merge which I sometimes need. The best merge tool I've ever used is Araxis Merge, but it costs $269 for the pro edition, I can't justify the extra cost vs the $30 Beyond Compare 2. Araxis Merge's price tag was worth it when I was working with an offshore team. I had to 3-way merge code from the US and India across many files and directories. It would have been too expensive in time if I didn't use Araxis Merge for that task.
