Listen to these guys!
As someone who is also building their first HT listening to the responses you've seen here is my best suggestion. They've already saved me thousands with their input.
Based on some research (and feedback from this forum) I have gone with the following:
Panasonic PT-AE1000U Projector: $3500 @
www.projectorpeople.com and comes with free Oppo 981HD DVD player
Axiom M60 speaker package for front,surround, and center channel $2600 (with mounting brackets and 7.1)
Dual SVS subs: PB12-NSD $1200
Carada screen: 118" for $900 (excellent value and performance)
Blue Jean cables for everything cable/wiring...great prices.
The performance is more than I would have ever expected for my 16x19 room and only cost $8000.
