I would suggest Optoma HD20 High Definition 1080p DLP Home Theater Projector
True High Def 1080p Resolution
1700 Lumens Brightness
4000:1 Contrast Ratio
Up to 300-Inch Screen size
Gloss-white finish. Low-noise fan on normal-bulb mode. 4000 hours lamp life on econo is greater then most projectors! Good enough to use in bright mode to use with lights turned on in the room. In the dark, it looks simply amazing. You can use it with white wall or if you can afford then buy screen

or if you can afford another good choice is Sanyo PLV-1080HD High Definition 1080p LCD Home Theater Projector, a great HD LCD projector.
Full 1920 x 1080 HD resolution with TopazReal technology
10,000:1 contrast ratio for rich colors and deep blacks
