here is what I have and it is only 720p but looks amazing with blue ray dvds
Mitsubishi - DLP Home Theater Projector
the 1080's will run you around $3k though new.
and the screen I bought was this
AccuScreen 106" Diagonal HDTV 16:9 Fixed Projection Screen - Black Velvet Frame
I had a non HD one for 3 years and bought this a year ago and it is nice!
If I were you I'd be careful buying a used one or atleast know how much a new lamp is for it before you buy cause hour meters on those things are easily reset
