The sony DRU-800A is a rebadged lite-on SOHW-1693S. http://www.newegg.com/ProductSort/SubCategory.asp?SubCategory=5
Its a sony model DW-Q28A. Just picked one up to replace my DW-U10A. And I just love it. I paid $41.99 but I think they can be had for a couple of bucks less now. I've only made a few burns with it to test it out using Decrypter and Shrink. I set Decrypter to burn at 4X but the actual speed was showing to be 6X with Sony disks. Compared to 2.4 which was my old burners top speed, this is like warp speed.
