This is just the kind of thread I've been looking for. I know I need to calibrate my monitors, (I would rate the built-in software utility in OSX as barely OK, I also hear the Win7 one provides much the same end-result) I just need to know which direction to take...

Anyone used multiple products and have a preference? I'm using a Dell 2408WFP for 99% of my work, but it would be great if I could match the 13" MBP colour reproduction (I think it's not quite possible without crippling the Dell). I may need a tool that can not only calibrate my screen(s) but help me set up some printing profiles as well.
