PeekIt
Geeks Gotta Love It! A Free Hex Editor... and Much More
Update 10/11/07. I actually made this decision a few months ago, but I'm running behind in posting stuff. Peekit is a great tool for taking a look inside binary files, especially those that aren't mach-o executables. It's relatively easy to extract or modify text in such files. I used this to figure out how to modify FastOrSlow's icon to be white instead of black for Crystal Clear. Horrible icon, but hey, not everyone's an artist. It's just that usually they aren't Mac users. :-)
Version as tested: 2.5.4.
