@HoodedCrow,
Too bad you didn't come to AmiWest last year. They had about a dozen A2000's that all (or most) had working hard drives w/SCSI controllers, for $20.00 each. I almost bought one just for spare parts and chips, but with me already owning 18 Amigas now, I could not justify the space requirement for just one more.
You might try to contact the Sacramento Amiga User Group who were selling them to see if they still have any to sell.
