Extended warranty for Plasma TV?

We have a 50" Hitachi Plasma that is 5 years old. When we bought it we purchased the extended warranty that will expire Feb.11th this year. We have not had one single problem with the TV. We have the opportunity to extend the warranty for one year at $99.99 or two more years for $179.99.

This is through Best Buy and the Geek Squad. The main reason we did the extended warranty in the first place is if we have a problem and they cant fix it at home they take care of all transport to and from the repair place, for a 50" Plasma that can get expensive fast.

So the question is...do we extend again. What would you do?
