I just purchased a new DVD-Rom from Newegg.com. I was expecting to get a LiteOn XJ-HD166S, but instead I got an XJ-HD165H. Are there any big differences in these 2 drives? Is it worth the shipping cost and time to send it back and wait at least a week to get the correct drive? If the 166 is a better drive, please tell me. I know a lot of you will probably tell me to send it back and get what I paid for, but if the 165 is no different I really don't see the point in wasting my time. The manufacturing date on the 165 that I received is Jan 2003.
