Pantone huey - The Digital Photography Weblog:

If you're anything like me, you struggle a bit with colour management. I'm yet to invest in a proper tool - my current method revolves around checking my main monitor against a reference image that I keep around for that very purpose - not astoundingly accurate, but it's doing the job so far.

I know I should invest in proper colour calibration kit, but it's just another thing to buy, another thing that I really shouldn't spend too much on. So the introduction of something in this price range is rather welcome.

Of course, I'm a sensible type (as well as being cheap), so I'll wait for a few reviews to come out before I whip out the credit card...
