Sorry to hear about the heart problem dude. hope you get well soon. I use the IO Data SCSI2IDE Bridges as well. I have noticed that these are the only ones that seem to work on the Amigas. I've tried 3 other brands and No Dice.
I use them with a IDE to SATA adapter and they are awesome. the speed is amazing.
I have an 80 gig on my main a2000 and a 40 gig on the other one both running OS3.9
