I once made the mistake of buying the cheapest samsung 720p 50 plasma (the last model before the 51 incher) about 3 years ago, and sold it just over a year later. Overall the PQ wasn't bad its just that I started to become dissatisfied with all the limitations of 720p units over 1080p units. I started to see the screen door effect, a fuzzy picture and mosaic patterns in big patches with all colors (blacks mostly). Anyway I would never buy a BIG screen 720p again.. All major brands sell the same model in 720p and 1080p, the 1080p is without a doubt better and cost more, so that only means buyers are buying by price not PQ. Since a big screen is something you will use a lot it pays to buy what you really want.. Smaller screen sizes maybe somewhat acceptable in 720p, but a bigger screen will just magnify the shortcomings of 720p units. So don't let the lower price blind you, like it did to me.
