There's and old saying 'that the best (product) you buy is the best one you can afford"
It's abit like buying a new PC and not knowing what's the best. It all comes down to "what you are using it for?" I'm hoping to get a Hanns.g 19" since the price in NZ is pretty good. Viewsonic are also highly rated... It just depend's on "What you want to do with It :)"
