Hi to everyone, I searched all the forum and I could not find specific buying advice for JVC projector: I came across a store which sells new JVC X30 and new JVC X9 for the same price (I'm not too interested in 3D and I watch only documentaries and movies). The main differences between the X30 and X70/X90 are contrast and 4K. Since the X9 has better contrast than the X30, and both don't have 4K, I would assume that the X9 is better suited to my needs than the X30. Please advice and comment! Help me chose what's better for my needs. Thanks in Advance!
