Well, this will sound like an extrememly silly question, but here it goes anyways. This sounds like some kind of myth or fairy tale of some sort, but I have to know. I was in Best Buy yesterday looking at TV's. I havent decided what tv to get yet, but have been looking. Will probably crack by the Holidays. One salesman came up to me. He seemed slow (he was still babbling on about S-VHS as if it was some new technology), but what can you do? Anyways, he advised me against Plasmas. He told me that I would have to take up the TV up to the local gas station to have it refilled every 500 hours??? He also advised me that plasmas are also known to cause gas leaks and house fires??? He advised against hooking up to tv to a house gas line. I actually did laugh because this all sounded like some kind of joke. Is there any substance to what this salesman was telling me?
