Quite a while ago, I replaced my CDR with a Pioneer DVR-105, but the latest model out is a DVR-108. You can buy one for less than US$100. Look at dealmac.com for the latest pricing, or go to newegg.com or macsales.com. Replacing the drive is no big deal. Just keep track of what you are undoing, and then substitute the new drive and re-do what you undid in the reverse order. The only problem that I had was getting the front plate to line up with the door, so that took a bit of jiggling around. Maybe added 5-10 minutes to the process. --Steve
