Wow, this is a great projector. Image is sharp as a razor, bright, and has very good contrast. A major upgrade from my Infocus 777/Kodak 333. Have not tried the 3D yet, just not that interested in 3D really. Avscience is a great company to do business with. I'm no expert and have not seen a lot of different projectors, but I can not imagine anything better than Sim2.
