You can get a very good plasma set that will handle 480p or 720p for about 4 or 5k. This should be much betterthan your tv if it DOES NOT handle 480p. Head on over to
www.hometheaterdiscussion.com and post your question. you will get lots of replys. Also, if you can go an extra 1k, you might want to get a DLP projector which will blow your tv away.
