Digital camera profiling packages

Does anybody have any information comparing different camera profiling pacages? I see that that there is one from ColorEyes, and gretagmacbeth has two packages (maybe more) that do it – Eye-One Photo and ProfileMaker 5 Photostudio. Any comments on the differences between these packages or any other packages available?

What’s really nice about the GMB product is the options for building the profiles and the ability to measure colors in the scene to use for building the profile (you’ll need an EyeOne Pro Spectrophotometer).

Eye-One Photo or ProfileMaker 5 Photostudio? What are the differemces between th two?

ProfileMaker Pro (whatever Package comes with the camera module). I can’t keep track of all the variants.

Thanks. Have you ever tried ColorEyes?

Nope.
