From reading posts on avsforum, some Samsungs are only getting about 100 hours on the bulbs, and they are hard to find. That's about the only bad thing I've heard about them. 20 yr life span is laughable at best, I'd of told the salesman to go bother somebody else at that point and leave me alone. Now if it had a 20 yr warranty then I'd think twice about that statement.
