I have been using an IPF8000 for about a year now and make all my own
profiles with Monaco Profiler 4.8.3. I think they look great.
Yes, another best kept secret, IMO. Especially if one plays with and
uses Perceptual rendering. In some cases, MP's 2 step profiling with
customized target generation has unique advantages.
I tried PM5.x and Bills targets but I preferred the Monaco Profiles
myself.
FYI, you can use Bill's 1728 Monaco friendly target, measure in
ColorPort, convert the measurement data to Lab using his supplied
script and import in MonacoProfiler. I have found the results to be
slightly better than with XRite's 1728 targets.
