If you have DVI the Bravo D1 (for $199) gives an incredible picture that many reviewers see as equalling or bettering almost anything else out there (check reviews in Widescreen Review, projectorcentral.com, or go to avsforum.com for much discussion).
Two caveats: the component output is poor, and there have been reliability problems (tho' mine has not given me problems).
Good luck,
David
