I use Nec Spectraview Reference 271 screens. For pre-press and retouching jobs, I think it's of utmost importance to use tools you may rely on. I could test Eizo ColorEdge and Quato Intelliproof screens too, that are equally good, but the quality of the matrix being different (too sharp on Eizos and too blurry, CRT-like on Quatos) I preferred and got used to Nec screens.
They are really worth it! And Spectraview Profiler (rebranded Basiccolor Profiler) is just precise, accurate and powerful (using DTP94 and Discus sensors).
