I bought it - and it does a good job. As to how well it works on an LCD
monitor - that really depends on what controls the LCD monitor has (eg can
you adjust individual colours?) - but if you've already got the monitor it's
going to be a moot point, as all calibrators will have the same limitations.

Having said all that, you might find the following news release of interest
(keeping in mind that the $250 mentioned is NZD - prob about $175 US)

Pantone release new "huey" monitor optimiser - for under $250
Pantone also had a big announcement over the summer - they have dropped the
ColorVision Spyder products and have joined forces with GretagMacbeth to
create the "huey".
Huey is an entry-level monitor optimiser that brings monitor profiling
within reach of everyone - from amateur photographers to gamers; although I
think an Eye-One Display 2 or an Optix Pro would be better suited for
serious amateurs and professionals.

The huey is a pen-sized monitor optimiser that is easy to install, easy to
use, and creates a monitor profile in less than three minutes. It also has
the ability to remain hooked up to the computer, automatically adjusting for
ambient light levels in the room.

 What did he need to upgrade?  I have a Monaco Optix, and when I upgraded
to XP, the software worked perfectly.  When I upgraded to the x86-64 edition
of XP, I emailed Monaco, and their support sent me a 64-bit driver as well.

 According to Monaco, the driver is considered finished and stable, but
hasn't been released yet.  However, they do supply it upon request in
exchange for feedback, and it also worked perfectly on my system.

The Monaco optix bundle includes software for creating custom printer paper
profiles using your flatbed scanner. With some printers (e.g. any Canon)
these profiles work better than the manufacturers canned profiles (which is
exactly two for Canon- matte or glossy). I have used both Spyder and  Monaco
for monitor calibration and both work equally well, at least for me.
