It's hard to say with an LG; some rebranded drives are OEM Pioneer or Sony drives but since LG does manufacture some items it's probably unique.
Essentially any Pioneer drive except perhaps the very latest models (need to check, although drivers show up eventually in OSX usually) works. Some others as well. If you're willing to take on some extra work, many intrepid experimenters get quite a bit of hardware running and usually show you how.
