I've had the DW1650 for about a week now and really like it. I accidentally broke my Liteon DVD-ROM drive and had planned to replace with another DVD-ROM drive since I have a Liteon 8X DVD+/-R drive. But, the deal on the DW1650 from Newegg was too good to pass up.
Excellent read/burn speeds, and is much quieter than the old Liteon DVD-ROM drive. The only thing I don't like about it is the LED remains on when there is a disc in the drive, not just when burning or reading. Otherwise, it seems to be an excellent drive.
