External Mini-DVD Drives?

Anyone know of a small External Mini-DVD/CD Burner?

I have them for the larger 120mm Disks already. But I want a small one (palm sized) for 80mm disks only.

All I need it is to play Mini-DVD disks, if it can write/rewrite to them it would be better. But my searching has come up with nothing so I figured since this forum seems to be the right one to ask in if any of you knew about a drive that would suit my tastes.
