hi, with the price of plasma's falling does anyone know how long it is before they start to loose picture quality, has anyone had any experiences, i was tempted to buy a budget 42" one for about £2000 or so but was put off when told that they have a short life span and start degrading in quality. is this a pitch by sales people to push us into buying lcd? ps: i think some of the budjet ones have great picture quality! pss: are they good for pc gaming? any experiences?
