I went to a local pro for advice before I bought my last two monitors. My budget was $300-400, or so I thought. I was very unhappy with my 5-year-old 22 inch LG. He was using IPS NEC monitors, which were gorgeous. When I balked at the price, he asked why I would spend thousands on bodies and glass, but considered the price for a 27 inch NEC ($1000-1500), the one piece of equipment used to edit and view my photos, excessive. I didn't have a good answer for that. Eventually I went with the 27" NEC PA272W with dedicated X-rite calibration sensor. I'm not wealthy, so I continued to save for a while before making the purchase, but it changed my attitude concerning monitors. I was so impressed, later I added a 30" NEC PA302W when I found one at a sale price that equaled the sale price of my 27 inch (both use the same X-rite sensor). Honestly, I can't say how much better these monitors are than a cheaper Dell, but I'm overwhelmed by these every time I use them.
Prints were always a problem with my old monitor, especially matching the exposure and color to the screen view. Lowering the brightness to a known, repeatable value when calibrating the NECs fixed this. Whatever you decide to buy, calibration isn't an option - it's a must.
