From the other TV thread...
Panasonic's plasma model numbers work like this
X: junk, do not buy it
U: bottom end
UT: I think this is a U with 3D
ST: low end
GT: mid end
VT: high end
I think you will have to spend more money unless you have an idea of good picture quality that doesn't match a dedicated videophile's expectations. I advise against buying a 768p plasma like the X.
With that budget you could afford a P50U30Z. It is available for $1600 but is periodically available for $1500 or less.
