That would be a 2006 model, which is important for parts replacement.
I would suggest looking at Other World Computing (Macsales.com), as they list upgrade options per Mac model.
Pioneer BDR-211 lists only Windows compatibility, that I could find. That might be important for driver software, drive utilities, and firmware updates. LG WH16NS40 lists Mac OS X 10.6 or later compatibility, so that includes Lion 10.7. Seems like a good choice.
