I can't believe that I paid 100EUR per piece.
The reason for that is that the IDE and SCSI protocols are different; so it's not just a simple wiring interface, the adapter actually has to translate. If you add extra electronics in between, then obviously that costs money and the price will be higher. SATA->SCSI adapters should be cheaper, as they don't need such logic (SATA really is a SCSI variant). There will probably stil be some logic in between to read the SCSI command on one interface and rewrite it on the other (SATA isn't parallel scsi anymore, so there _is_ a difference), but that logic should be simpler and thus probably not as expensive. Alternatively, CF->IDE adapters don't need to translate at all, so if you need IDE I'd suggest doing that. I bought two of those for about €10 apiece (IIRC) a few years back (they're in use in two powermacs). Make sure not to go for CFast, though, since that's SATA, not IDE (and physically incompatible with CF). -- This end should point toward the ground if you want to go to space.
