Dan Attis has given several presentations to the various user groups (VB, C#) of his favorite dev tool - CodeRush. This, plus the demo I saw at TechEd 2005 where one of the DevExpress people was flying through code so quickly I had trouble keeping up, made me want to try it out. Of course, in my typical style I procrastinated until recently. I love it and I'm endorsing it for everyone else out there.
