Sound and Vision recently had some quality time with Panasonic's mainstream 42-inch high-def plasma. (TH-42PX60U) They ran the best selling plasma through the paces and came to a conclusion. While it is not the best, it certainly is not the worst but rather "fairly typical." They did indicate that it is a tad bit overpriced considering its performance and educated buyers will probably look elsewhere.
This is a very popular plasma so if you are in the market for a new flat panel, this is a must read.
