Hey guys, I recently purchased an apple 24" ACD and I've been kicking around the idea that I'll be well suited to purchasing a calibration device to set that and my MBP? Thoughts and/or opinions on this. I'm an amateur photographer and in the past I've really made a huge issue of calibrating my monitors. The difference now is that I see a clear difference between the two montiors (mbp + ACD). I've narrowed my selection to the spyder 3 pro (or elite) and the i1 display 2. Any thoughts or opinions on these two, or perhaps recommending a different model (or not even recommending any model). As an addendum, I don't do too much print work, I have a good printer and I'll print some images, but most of my stuff is online. I'm not sure if this factor makes any difference.
