Well since we're expounding on our favorite utilities, I'm extremely happy with "ExamDiff Pro", my diffing tool. They added a really cool feature that allows for plugins, so you can diff far more now then just text files:

Text File Sorting
XML Canonicalization
HTML and XML Formatting
Adobe PDF to Text Conversion
MS Word to Text Conversion
MS Word to Text Conversion (alternative)
MS Excel to CSV Conversion
MS PowerPoint to Text Conversion
Compare ZIP, Java archives (requires ExamDiff 3.4 or higher)
Compare remote files by their URLs (requires ExamDiff 3.4 or higher)
Compare remote directories by their URLs (requires ExamDiff 3.4 or higher)
Compare Windows executable files

I'm in the process of evaluating "Directory Opus", which appears to be a very cool replacement for Windows Explorer. The manual is almost 300 pages. It's a little pricey, around $60, I think. But it already makes a couple things I do regularly a lot easier.

>I know this product has been recommended a few times on the UT and I bought a copy of it today (version 8) for a project we're busy with. What an absolutely awesome product for screen capture and related functionality. Very highly recommended. http://www.techsmith.com - US$40, a bargain.
