You can see the differeces here. Yes the diff is 1655 is LightScribe. I have a DW 1620 and a DQ60 I recently bought. I was confused about the different models and the salesman was not familiar with the finer points and I took the DQ60 only because it was the most recent model on their shelves. If figured LightScribe was pointless, since the guy told me it only works on Benq discs, and not everybody stocks those around here.
