At work I deal with multiple Excel workbooks tracking inventory data so they bought me two Dell 34 inch wide screen monitors. Then I come home to my 24'' monitors. Once you go wide screen it's hard to go back to little screens.
For my back room I bought a LG 34 inch wide screen and man is it sweet. It is only 2560x1080 but it's pretty clear and easy to read. They have some higher end LGs with better resolutions depending on how much monitor you want. I recommend them as it was one of my better purchases this year.
