I also coughed up a modest amount for Nick Bolton's Mailwasher, thus receiving MWpro free when it came out, and then getting Firetrust Benign for the
offer price of about 7 quid. The latest deal has brought forth
MSGTAG Status for 29 quid, and very nice it is, too -- if still a tad pricey when compared with the features of the Free and Plus versions.
Sometimes, it really does pay to support the authors of the software you use. Mind you, I was one of those who paid Justin Frankel USD 10.00 for a Kosher version of WinAmp just 6 months before it became freeware!
