I have walked the SCSI-path myself and find it a great way to expand your Amiga. Especially when you are able to find the optional SCSI-board to connect to your Blizzard turbocard, the results are great. I now have my A1200 connected to a grand total of seven SCSI-devices, which completely fills up the SCSI-chain. This includes a harddrive, scanner, cd-rom and cdrw-drive and three different removable drives (zip100, sq3270 and a 230 MB mo-drive).
SCSI rocks big time with your Amiga and gives a much 'neater' setup compared to IDE-flatcables dangling around the exterior of your Amiga...
