Plextor PX-716UF
http://www.plextor.com/english/products/716uf.htmThat is what I am looking at. Both are $160ish with the plextor at 230 The only thing that I dont know about is the sony's quality.. I had a friend who had one of the original sony cd-rw drives and it was so picky about media.. the sony does look like the faster drive.. but the hp has litescribe.. or what ever they call it..
