I'm also going to endorse NUIX's ProofFinder utility as hands-down one of the best "for the money" tools available. I use it primarily for email conversions but it's also great for searching/investigating data sets. It could easily be sold for more and still be worth the money compared to other tools in the category.  

Hi all,

As promised, after the trial of Nuix Work Station must say that the email part of is great. Especially graphical charts of all email correspondence

I would recommend Nuix Prrof Finder to everyone interested in email analysis to try it, great tool that is..
ntexaminer – thanks for your tip off !!  

Another vote for NUIX Proof Finder - I've purchased the "charity version" and found it very useful and effective.
