Actually, that is probably up two levels ;-)  I just recently got an
Eye One and  so far it's been great. For the linearizations, but also for
calibrating the monitor  and scanner.

Next level up from the scanner is probably an X-rite 810.  Not as
good as the  eye-one by any means, but in practice much, much better than 
the scanner  (epson 3200) for linearizations.  At less than 20% of the price of 
an eye-one (used on ebay) it  is not a bad option.
