I've seen numerous postings by new Alpha owners who have SCSI needs as a result of purchases from Onsale.com. If you enjoy the auction atmosphere, try www.ebay.com. There you can find used (some new) scsi2 drives, external cases, cd roms, etc. No, I'm not an employee, nor is this a paid advertisement. But, I have found external cases for under $20.00 and 1gig drives for $30 which were in nearly new condition and worked like a charm.
Just an fyi,
