I have been quite happy with both my drives:
My optorite 0201 .... despite the many problems people have with this drive, I have found it to write most disks I threw at it rather well. I used to have problems with it coastering 1 out of 5 disks, but those problems seem to have disappeared with cooler weather and the latest firmware. (not sure which one is responsible for the improvement) My main gripe with it now is that it is slow reading DVD+/-R's and it can sometimes lock itself up, requiring a reboot.
My new pioneer 108 ... very nice burns and a much better reader then any other DVD drive I have owned. With the pioneer being such a new drive, its performance can only improve as time progresses.
