I like the Optoma RPTV as well. I have installed a few Sony GW 50 and 60" and found they work best in a darkened room. One customer built a custom cabinet next to a bank of floor to ceiling windows. Watching the television during the day was completely useless with the blinds open. Picture was completely washed out as if he hadnt turned it on. But in a darkened room, it was one of the nicest pictures ive seen.
