I'm in the process of getting a projector. Avsforum is a great resource but tends to get a little fan boyish. Some of the threads become a tebow vs orton type pissing contest.
Hardest thing about this entire process is being unable to comparison shop. Most stores like best buy or fry's only have lower end projectors on display in less then ideal settings. Plus their demo's have been running who knows how long which can really affect the lamp lumen output.
Right now I am debating on the new sony hw30es or the panny 7000. Smart money say wait til more models come out is year, but that would mean missing the first half of football season on a 100 plus inch screen!
