I had a similar issue about a year or so back ... the monitor that solved it for me, text-wise, was my Doublesight DS-265w. It's a 26" IPS monitor with a native resolution of 1920x1200. I didn't like the text on my former 30", IPS 2560x1600 Dell 3007WFP-HC or my 24" S-PVA Westinghouse L2410NM, and wanted something kind of in between, yet better than both. I guess in my case, having the 1920x1200 resolution, but in a bigger (26") size than my 24", was the key issue.
