I'm trying to choose something to calibrate my Monitor, so I can get better prints with my brand new Epson R3000 printer. I'm currently running a late 2010 dual quad-core Mac Pro running 10.6.x, and for photo's I currently use Photoshop CS5 Extended and Lightroom 3. While I'm not running 10.7, I'm sure at some point in the future I'll upgrade (currently no reason to, and a couple very good reasons not to). I've narrowed my choices down to the following. Pantone Huey Pro Spyder 3 Elite Colormunki BTW, you quite honestly you do not want to read Amazon reviews when trying to choose a monitor calibration system. Zane -- | Zane H.
