you can use larger drives, SCSI or IDE, with the A2000, the key is twofold:
1) keep partition size at 2GB or less - even with the TD64 patch, partition size has to be <2GB, an AmigaDOS limitation
2) use the TD64 patch (FFS 44.1) to allow drives larger than 4GB overall to be used.
Good luck at finding a new drive at under 40GB, though. IDE would be by far cheapest over SCSI.
I recently put a 40GB IDE drive in my A2000 w/ a buddha and it works fine - I didn't bother to create partitions on the entire drive, just created 4 at just under 2GB each - I can always make more on the unused capacity as needed later, after all.
