I've had experience with older projectors, and InFocus was one of them (the older tech doesn't hold a candle to the newer projectors).
The key for you to choose would be to go to a showroom of an office supply/electronics shop and connect your laptop to it.
Colorsync will be your friend in getting the best color output possible. Then you should simply compare across the offerings they have.
Sorry I don't have more recent experience, but I think you'll find something in the light range that will do the job.
