I am biased, of course, but I'm using a Plus UP1100 which can be found in that price range and I feel offers a very nice image. Now I am also using a scaler, so I can't speak for what it would look like without. I don't think there are any DLP projectors in that range that will look good without some type of outboard processing, but maybe I'm wrong.

Good, cheap, easy - pick any two.
