I looked in to plasma tv's a couple years ago. The salesman finally gave me the answer I was looking for...longevity of the plasma tube. Though it had a warranty of one year..the replacement tube had no warranty at all. In other words, it would be replaced one time. The replacement cost was over $1000 with no warranty.
