After months of riding the fence, I broke down and bought the Panny L300u. My prior projector was a Sony 1252 CRT. So far the uncalibrated out of the box picture is very satisfying. The projector is mounted about 1 foot behind a ceiling fan. In the process of mounting the projector I noticed a TON of collected dust on the fan blades. What is everyone doing with their suspended projectors to protect them from the dust? What is the best way to prevent the dreded dust blob?
