I've heard the stories that Plasma gasses leak and can result in a TV that only lasts 4 to 10 years. Like most people I love the picture, but don't want to spend that much for such a short lifetime. I did a quick search, but couldn't find what I was looking for so maybe someone here can answer my questions.

1) What is the expected lifetime on a Plasma TV these days?
2) Do any Manufacturers offer a way to recharge the plasma?
2a) If so, how much does that cost.
3) Which plasmas last the longest?

Thanks in advance!

Also if you know anything about Projection TV's, I've heard that LCoS technology is better than DLP, but I can only find high end LCoS TV's on the market.

1) Does anyone make a cheap LCoS that I can check out.
2) Are there any shortcomings to LCoS (like life expectancy, pixel loss, etc)?
