As the ad states - if you don't feel comfortable then don't do it. As far as price goes .... I suppose actually putting a price would be better I can't disagree with you there. But then again take a qucik gander at all the TV's for sale. Some people have old 19"'s for $45-$60 where as other people have ~$25.00. And again I ask - how does a person not go butt broke buying to TV's to realize the tubes are incompatible? I see the listers side also.
I just wanted to chime in about the whole "RED WIRE BAD going to kill you" mentality. I've been hit with 19.5Kv. It sucks no other way to say it. It was truly my own damn fault trying to use an HV probe. I have never EVER been shocked by touching the Anode wire. It's shielded. If people are that worried about getting shiocked then don;t ever touch an extension chord - it's shielded too
