The 58" panasonic full 1080p plasma can proboably be bought at 6th ave electronics (RT 4 paramus NJ) for $3500 or so if you haggle in person. The pioneer elite 60" in either 1365 X 768 or the full 1080p will have a better scaler but probably will cost a $1000+ more. Check their sales online as they often clear out plasmas during holiday sales.
I prefer plasmas to LCD's (which are getting close but still look artificial IMHO) and I'd skip the projectors (DLP's etc and front projectors) if 60" is enough.
Samsung and perhaps LG make 63" plasmas and pioneer makes 65" and even larger plasmas are available but you'll pay a huge premium for anything over 60".
