Ok, then you have a relatively wide choice at ebay or even some remainder at a retailer.
My first choice would be the LG GH20NS10 or LG GH20NS15 (or the equivalent Lightscribe models GH20LS10/15).
If only because of the slow recommended DPM speed (and the age!) i wouldn't go for the Toshiba.
Beyond that the DPM files of the LG and Optiarc IMO are better than the Toshiba ones - at least for DVDs.
P.S.: In a thread in the Customer forums a user also mentions the GH22NS40 as a good DPM device
