Hey guys - the wife and I are considering diving into the home theater realm. The picture will be first. We'd like to take advantage of the wall just above our fireplace - which means there's only two choices. Flat screen or projector (don't worry, it's a deep double-sided fireplace, with very little chance of heat or soot affecting anything).

We'd like a plasma, but they're expensive. However, projectors can be expensive as well - and from what I've seen, projectors are very succeptible to lighting and glare problems. The spot we have open is about 48" square. Any suggestions or recommendations either way? We'd like to stay below $4k.
