Well I purchased a DVD-R UJ-812B from .(JavaScript must be enabled to view this email address) on ebay for 130.00 plus shipping. A very good price in my book. I have included some photos as I went through the process. The DVD-R needs to be modified unless you get an exact drive from sony. It is easily modified with a good set of scissors or tin snips. I used scissors and cut off the edge. You will need to take the top cover off the new drive.
I hope these images will help others. When you snap the case apart be careful right next to the wireless switch and sound output jacks, there is a plastic snap there. You will also have to unlock the keyboard cable (pull up on lever) and the trackpad cables (2 which just pull out.)
Works great so far. Hardrive can be upgraded when the new ones come out. It is tuff taking the plunge to take apart something this expensive.
