I bought the 5UY version about a year and a half ago (for $4400 shipped...ouch). This display is incredible. Colors are deep, and blacks are BLACK. Yes, it is EDTV resolution, but it will accept 720P and 1080i signals and downconvert them. I also have an LCD HDTV, and frankly, HDTV signals look better on this plasma than the 'true' HDTV. The best part about HDTV signals is the native widescreen format, progressive scan, and better sound anyway. I mainly watch DVDs on it, and DVDs are in 480P, so they actually look better on an EDTV than an HDTV (since HDTVs have to upsample). Of course, when HD-DVD or whatever comes out, then it will be a different story. But that is years away.
For $2200 shipped, this is a steal. Panasonic makes the BEST plasma displays.
