Austin Chronicle has just done a very nice little guide to Home Theater Projectors. Behold:
Your home is your castle. But what about your movie theater? With portable projectors, you can create a theater in your home that's almost as good as the local cineplex. Inch for inch, projectors deliver more bang for the buck, although replacement bulbs can cost $200 or more. For example, a typical 42-inch plasma television can cost about $3,000, but a projector will get you a 200-inch picture for less than $2,000.
