For a classic Amiga, I would go for the SCSI-route, especially since you already have the SCSI-expansion to your Blizzard 1230. SCSI is easy to set up, reliable, fast, flexible and most of all: expandable.
I have my A1200 setup with a host of SCSI-drives (7 in total), ranging from zip to jazz, MO to cdrw. All work flawlessly. The same goes for my A2000, which has a range of different types of drives connected.
