I have a lot of SCSI drives 2gig, 4.5gig, and 9gig. They are all 68 pin wide and I have used them for my A4oooT and they worked great (with a 68 to 50 pin adapter, I will see if I can locate some of them, I have cleared out majority of my Amiga stuff). You can have what you like for cost of shipping, not sure how much it would cost to ship across the pond, I live in Canada.
PM me if you are interested.
