Looking for a place to get small(-ish) SCSI drives

I fool around with a lot of systems that want small (by today's standards) 50-pin SCSI drives. A few years ago you couldn't walk around the streets of Palo Alto without tripping over big stacks of 500MB drives. These days, though, the stacks are made out of 9GB SCA drives -- far too large for my needs, and often far too large to be recognized by the computers I fool around with. But drives smaller than that are suddenly "rare" and "expensive", $30 or $40 for any SCSI drive under 9GB at a lot of resellers I've visited lately. Anyone know where those stacks went? Are small drives just impossible to come by for less than $30 now? -Seth -- "It looks just like a Telefunken U47! Seth Morabito You'll love it." - Frank Zappa sethm(a)loomcom.com
