That's a GREAT deal for anyone who is looking for an HDTV! As long as you have the room (they're pretty big) for it and don't care if you can't hang it on your wall like a plasma, you should go for it.
I still think that CRTs have the best quality HDTV pictures out of all of the different sets. The only drawback is that you need the room for them and you can't get them any larger than about 36". Still, it's a great cheap way to go HDTV for your 360!
