Sadly in the rush to low prices, quality or rather 10 to 20 year designs are a thing of the past. You rarely see more than a 1 year warranty and think carefully what they are telling you. The stuff I see inside is about a 5 year design. Any more than that and we may think we're lucky.

As to cost of repairs. As the prices of service went up and the product prices came down, folk are a little put off at the result.
