The screen I selected was the DaLite Model C With Controlled Screen Return, Video Format. Here is the link to the site and exact screen,
http://www.thefinalclick.com/shop/customer/product.php?productid=83220&cat=10623&page=1 It’s another great site and they are happy to help you select the proper screen based on your lighting, projector, etc. I am very happy with the Pana AE900U. I don’t think I will need to upgrade for at least another year. The AX100U is the successor. It has top reviews (I believe after rebates you can get it for about $1600). You can get the AE900U used (eBay) for under a grand. Replacement bulbs are about $300 or so. At projectorCentral.com there are links to help one with the build of inexpensive screens. Before I decided upon a screen, I used a white wall and the image was quite fine. Now, we still have an old TV that is for most of our viewing. We use the projector for movies and interesting shows on the HD channels. Hope this helps.
Very happy with the Panasonic AX100U ($1300 after $400 rebate) and Oppo 981HD and free ceiling mount I received last week. Still need to get a screen (white sheet OK for now). While a 5.1 ch audio system with AV receiver is six months off what do you have/recommend?
Thanks for your help-steered me in the right direction. Freepers rock.
