Im using a Plexwriter 12/4/32 external with my EMU...work's wikid.
they have internals as well cheeper...just put it in an scsi case or get one of them single unit rackmoutable cases that support a scsi cdrom.
Most of the time tho i just copy the entire ROM disk to my bigassed 60gig seagate IDE drive in the EMU.
