Query: Beware of Sony DVD burners!!!

My Sony DVD drive is not even 2 years old and has now stopped working. For me to get it fixed, it will cost me $20 for them to troubleshoot it and $170 to fix it!!! That is more than it costs to buy a new burner. The warranty is only 1 year. Their customer service is also horrible if you ever have a problem. I just want to warn people before they go buying Sony computer products.
