The scsi is just killer. I have a friend with one and it's fast! Of course, he had to add a card (Advansys for about $50) to his system, but now he's set up for other scsi peripherals.
I thought scsi was pretty much the way to go before they came out with the burn proof technology. It definitely raised the stock on EIDE burners. I hated buffer underruns! :|
