Don't get PLASMA's. From day 1 they get worse as the gas depletes. By the time they have hit their 50% MTBF the brightness has nearly halved on them
Not to mention the screen burn problems with dogs.
Lol I advised my dad to get a Panasonic TH37PX70 as it wipes the floor with lcd for SD which is all he watches. He went into the shop and the salesman said "don't get plasma it needs toping up every 2 months and if you have the screen at an angle all the plasma falls out" I mean wtf!
