The Fusion Reactor folks have released FusionDebug today. The price isn't bad - 299 - but one of my numerous spies told me that if you whisper "CFCOMMUNITY" you get a 10% discount. Be sure to use that money saved for a good cause!
Seriously though - I was able to play with the early beta of this product (not the later ones) and it truly rocks. I'll post a screen shot or two once I get the final version.
