... gven that most seem to themselves require regular calibration otherwise they give faulty results?
I have a Spyder2 and an Eye One and neither one of them seem to be able to get me anywhere near 65k.
The Spyder2 is the better meter in my experience, especially with laptop monitor calibration, but with my front screen projector it has an obvious red misread, in that it tells me I need more red in my grayscale to the point that people's faces are tinted an obvious crimson ...
Why do we bother to buy these meters if they're just going to lose their accuracy in a relatively short amount of time?
My follow up question, is, of course: is there a relatively affordable meter that doesn't itself need to regularly be re calibrated?
