I have a Samsung "506" series drive that I like a lot, but I don't know if they still make them.
You should probably look for a Pioneer or LG model.
I'd get one with "M-DISC" support as well.
Only thing to be aware of is that some of these drives (some, not all) -may- require the use of -two- USB ports to deliver enough bus power to the drive to operate. They usually come with a "Y-adapter" for this purpose.
The Samsung drive above works fine with only -one- USB connection.
