I just purchased an LG GSA-4040B from newegg.com for $139.99
Great price, and the above review holds that drive in high regard, as do several other reviews I found! This drive even supports reading and writing to DVD_RAM, like the two drives I have now removed from my system. I have always liked the usability of DVD-RAM, and since this drive comes with one 4.7gb DVD-RAM disk, I'll be using it for backup, most likely.
