You may hate this but a CRT is the best thing for editing Photography. I found a 24 inch one at a computer repair store for $20.00. But the thing is I also have 2 LCD monitors and I try to sync them together at times because the dang 24 inch must weigh over 100 lbs so I do most of my net worthy work on a Polaroid that is 19 inches.
I thought CRTs were better, too, until I used Mike's iMac, which is at least 3 years old, but everything seemed so much clearer and brighter on it, that I decided to get my own. After using a small CRt for too long... no comparison! The quality of the monitor makes a big difference, too- the LCDs we use at work are awful, but they work fine for what we do there.
