It's kind of hard to say which dual layer burner is the best. Since the media just came out, and is not very available. But as far as price, you can get the NEC 2510A for $90. The Sony dual layer burner runs $199
khc93, I just ordered the Nec 2510a. Should be here this weekend. If I can find dual layer media I will give you an update on how well it works. I have the 2500a now. Never made a coaster after tons of back ups. Just wanted to move up to DL.
