What external DVD drive should I use my MBP's internal drive is broken? I've got an old MBP where the internal drive starts to refuse reading discs and stopped burning discs a while ago.

Now I'm thinking about getting an external drive (DVD-RW, USB or Firewire). Most of these devices don't explicitly mention Mac compatibility. According to this forum post, most of the drives should be compatible though.

I was wondering if there's some sort of "official" compatibility list for different versions of Mac OS X? I also read somewhere that OS X 10.5 and 10.6 are compatible with most of the external drives... is there some information about which devices won't work?
I've never heard of an external drive that wouldn't work.
