I just got a friend to switch to Mac and now that he's bought a G4 he needs a monitor to go with it. He'll mainly be working with digital video editing and the like, so it should be preferably a 19in and something high quality like a Trinitron or a Diamondtron. He has maybe $300 max to spend on it, so it might have to be refurbished or open box. Any help guys? Thanks
