Sharp PG-MB60X:

- 2500 lumens
- XGA
- 31 cm x 28.7 cm x 10.4 cm
- 1000:1 contrast
- 2000 hours lamp lifetime



Acer X1260:

- 2000 lumens
- XGA
- 26.7 cm x 18.7 cm x 8 cm
- 2000:1 contrast
- 4000 hours lamp lifetime



What am I not seeing? It's got slightly less brighness, twice the 
contrast, twice the lamp time, and it's about 60% cheaper. Does not compute.


PS. Why do all the "DLP" projectors have 10x the contrast ratios of 
"LCD" projectors??

PPS. Not one single product description includes noise data.
