I've got a Formac ProNitron 600 which I got when I bought my G4 in 1999 (I think). I love the Formac, the display quality's great, the build quality's fine and they are cheaper than Apple. I think the model I have is discontinued now but as far as I know the new Formacs are still good (except for the cheaper 17" ProNitron, think it was the 200?). Anyway, as Azzgunther said, you can't really go wrong. The only think is (that I found when I was looking in to monitors) is that its probably more difficult to find a Formac stockist where you can go see some monitors and try them out whereas you'll find the Apple ones in any AppleCentre.
