I was just wondering if anyone has ever seen one of these 40-50 inch Plasma monitors with your own eyes?Just wondering how the detail is on one.I will Never be able to get one(unless I hit the lotto

,but I was looking around on the web,and ran across a few.Are these things worth 6000-1000 bucks?Just wondering what they looked like in real life.They sure look good in the pictures,but pictures are not always very accurate.One more question,what is Plasma,and what does it do?In other words how do these work?Thanks for any info,and in the mean time ill sit back and wish I could get one
