This years Panny Plasma are the best bang for the buck tv.....
The VT is top of the line .....
The ST is the best bang for your buck....IMHO
and the UT lacks the filter and wireless ....but its picture quality is almost as good as the ST.
Overall you can dial in with calibration a excellent picture with the VT...there is no better imho
But if your considering the ST or UT....the picture quality and black levels are pretty close to a VT.
check out AVS forums or HDjunkie....
another great tv is the Samsung plasma....the 6500 is their best bang for the buck TV
Plasma still has the best picture for a few more years...till the OLED come down in price.
Im currently waiting for a 50 inch ST Panny.......hopefully will be a Christmas ...boxing day purchase
