Maybe something in LED PJ might work for you, since you are just looking for something small and you can get a 80 inch widescreen at 8 feet back , 70 inch widescreen at 7 feet back, etc. It has 30,000 hours LED , so you don't have to replace bulbs every 3,000-6,000 hours. Realitively cheap on sale. Maybe look in pa70g thread or other LED threads. You could go with bulb, but it seems like you are looking for something to turn on and off anytime in small rooms to tv viewing/gaming/movies/internet surfing. The newer models like the LG pa75u are something that might interest you, it has built in tv tuner, wifi, bluetooth, 2 remotes, native 3d, maybe look at amazon and read user reviews and see what other guys suggest for you.
Wecome to the forum rooms, you are doing the right thing, and the guys here will steer you towards "legit" real PJ's and not some scam site. Name brands with warranties . The LG has 2 year warranty.
There is new LG LED that is 1080p coming out, but it will be around 1,000 dollars. The pa75 is around 650 dollars , and the pa70 is/was around 399 on sale. So, maybe keep your eyes open for the next few months for good xmas sales.
I'll let others share what they think might work for you. Good luck.
