Replacement DVD R/RW drive for a G5 (abaout 2 years old)

What's the best replacement DVD drive/burner for my Apple G5 (dual 1.25 processors -- approximately 2 years old) died... I was using a Phillips #509 DVD R-RW drive (a great deal for about $60), which worked fine but simply wore out. They don't sell that model anymore. Any suggestions for a new one? Many thanks.

Pioneer - DVR-116 or whatever number they are up to now. Internal yes? A little tricky to get in, but as long as your fingers are quite nimble you won't have any problems doing it yourself. I bought one last week - about $60 australian, so probably less if you're stateside.
