Hi, I'd like to buy a calibration screen tool to make sure that all assets I'm developing are true colour or at least close to the reality. I also print some pictures time to times but most of my work stay in my hard drive. That will be to use with my MacBook Pro & MacPro with Cinema Display LED 24". Perhaps with a screen calibrater I will develop more pictures in the future! Which hardware do you recommend for 100 boxes (GBP)? X-rite i1 is really good according to the review. Thanks!
