Read this thread as it devolves into exactly this discussion.
I ended up w/ an iMac, NEC PA241W, ColorMunki & BasicColor4 (which does the same HW LUT calibration that Spectraview does (and in fact, the European Spectraview s/w *is* rebranded BasicColor4)).
I couldn't be happier although due to lack of time, I'm still working on getting everything to match as well as I'd like but the NEC is amazing (big step up from my Dell 2209WA)
