Profiled two scanners with the cc24, a reasonably good Microtec 16bit and an inexpensive all-in-one Epson Artisan. I thought the results were good - interestingly (at least to me) not only did the profile correct color rendition, it also normalized brightness.
The two raw scans were significantly different in the rgb values on the neutral patches; after assigning the respective profiles to the original cc images and converting each to a sRGB, the brightest white patch measured out at 245 on both, second patch 200, etc. And the colors matched closely, all in all seems to be quite useful.
