When I bought my projector, I made sure I bought one that had 720p resolution for HD material. HD material over my HD Local Channel tuner is jaw dropping to say the least on my Z2. There are many projectors out there today that offer 720 or higher resolution.
I bought the Z2 for $1800 when it first came out about a year ago. You can get them now for closer to $1000 as the Z3 has been out awhile and the Z4 is about to hit the market.
I would suggest you go to
http://www.projectorcentral.com as it is one of the best websites to understand front projection and LCD versus DLP technologies. Also, they have great reviews on all the projectors.
Anamorphic lens's can be purchased anywhere from about $500 and higher, depending on the model you get. My prismasonic cost me a little over $700 smackers on a recent power buy that AVSforum was having. The screen material cost me about $70 on ebay, and the screen frame was less than $30 in materials I got at menards.
