I have a 52X true X SCSI drive. It was awesome, read most cdrs, and pressed cds, RWs had the most problems. It was very quiet yet fast.
Bought it for 49.99 at a compusa when they were closing them out, then ended up selling it for close to 100 on the forums when I got rid of all my scsi gear.
Kinda wish I kept it , but oh well.
