This drive (LG CED-8080B) is tested to boot and install OS X on my B&W G3. It doesn't support native burning in 10.2.8, but XLR8YourMac drive DB says that the drivers can be edited to enable burn support. I don't have 10.3+ on the B&W so I don't know if it goes to native support in newer OS versions, but PatchBurn 1.1 worked to enable iApp support in 10.2.8 for me.
The drive is a Dell OEM of LG so it's the model with the simple face plate, not all the fun buttons and lights of other CED-8080B versions. But, if it's going in a B&W or a G4, it doesn't matter anyway, right?
I'll take $20 shipped in CONUS. Otherwise, OBO + actual shipping.
