So, I've been thinking of getting one of these as I recently purchased a new 19" wide screen flat panel lcd monitor and have been getting more requests for photo shoots. I would like to increase my quality control a bit and be sure that with all the time I spend with adjusting images that when I get the prints back, it will be quite close if not a perfect match to what I see on my monitor. So, are these things worth the price? They range from 70-600$ and I'd like to hear from those who use it. I've played with adobe gamma to adjust the calibration, but still not sure if it is WYSIWHG. Also what's the difference between the different models and which is 'best'? So from those who have these devices, could you live w/o it, is it worth the money, or just an expensive toy that you could do just as well on your own with adobe gamma or something? Also, even if you calibrate it with the best device, the print is still going to be subject to your developers printer calibration correct? Wouldn't it make sense to use a good quality lab, like MPIX on a regular basis, and then maybe have a 16 (or so) block of different colors image printed and match your monitor to what you get back? Does that make sense? Like make a 4x4 grid of different colors, have it printed, then when you get it back, open the image and adjust your monitor to match what the print shows? I don't print anything on my home printer, b/c it's a cheapo and even if it were better, I can never imagine how it would be more cost effective to print yourself as compared to mpix. comments appreciated.
