I'm unsure what the "-0B" means, but if it's a 7200S then it's the drive you're looking for (excellent in my book! :D).
Plextor drives with Sanyo chipsets are considered to be some of the best-burning and toughest DVD drives ever manufactured, and the most significant ones are the PX-716, PX-755, and the last real "Sanyo" Plextor the PX-760 - unfortunately, these are out of production (OOP). Plextor units were often used in professional production environments which can be attested with drives' longevity (my Plex CD-RW is ~8years old) and high price even when sold as "used" - these are drives that would usually cost $200+++ (back when it was new) when consumer ODD were usually sold at a tenth of its cost. BenQ DW16xx drives also burn MKM media well, and like the Sanyo Plextors, are also OOP.
While the 7200S doesn't have the features that Sanyo Plextors and BenQ units have, it does its primary function well, and that is burning DVDs. ODD enthusiasts value Plextor and BenQ drives for their extra scanning features and the control they offered users in burning discs. While the 7200S can be hardly called a "professional" drive, it produces excellent DVD SL/DL burns and very good CD burns.
