Conclusion: Ultimately, the BenQ MS517 has its pros and cons and they are important to consider. Being a native SVGA(800×600) projector means it will be a little cheaper than other projectors on the market with higher resolutions.
Pros: Has a very high contrast ratio of 13000:1, Sharp image even when projecting higher than native resolutions, 3D from a Blu-Ray player via HDMI, Brightness readings were extremely close to the advertised brightness, Estimated 6000 hours of lamp life when running in ECO Mode
Cons: For very specific applications color may need a lot of adjustment, Resolution is low so not great for spreadsheets or teaching software applications, Lamp not very accessible., Not a short throw projector so the projector needs to be pretty far back to achieve average size 80″ diagonal image
Summary: The colour palette isn't accurate, and the native pixel count is too low for much computer-based use. But the attractively styled BenQ can handle light-filled rooms, and generally does a proficient job of projecting images.
