I'm sure this varies by area, but I was able to pick a Cendyne that is actually a Lite-On LTR-48125W.
It is easy to tell what is in the box because they print the model number at the bottom of the stick-on specification label. I had found another box that had a model number "CW4802" which is an Optorite 48x16x48 drive, but I wanted the Lite-On and eventually found a box with "LTR-48125W". The Lite-On rocks!
