For those considering expensive plasmas or LCD's, I highly recommend getting a HD Projector. The best one out on the market right now for the money is the
Panasonic PTAX200U
For $1300 you simply cannot find anything better to buy for home entertainment. Watching football on this thing in HD is awesome. The only thing better than this projector would be a native 1080. You'd probably have to pay close to $3k for a good one. Sometimes I 12 table on this thing. Here are some pics, although they do no justice:
I project this on a regular wall. If you don't have a big empty wall or live in an apartment, then get a good screen for around $250-$500 depending on the size.
