Summary: For a 50 inch plasma TV, coming from an entry level series, Panasonic TC-P50X1 performs quite well. With image quality that may suit a more expensive product, with quite decent features (although you cannot have THX certification or 24p cinema mode at this price), Panasonic TC-P50X1 represents a really good deal for the money spent.

Conclusion: We accurately predicted back in March 2009 that the price on the X1 720p models would be extremely compelling. We were right on that count for sure. The TC-P50X1 can be purchased for around $899 at Best Buy or Amazon as of June 2009. That is a stunner of a price when comparing with LCD TV models. The Samsung PN50B550 is $400 to $500 more but contains a 1080p screen and better processing.
