I have like piles of 90M DAT tapes floating around, mostly used once 
(the old job would do a backup, throw it in a filing cabinet - forever 
-great backup policy), probably several hundred of them.  If anyone 
needs 90M DAT tapes, I'll send them to you for free, just want to get 
rid of them (early spring cleaning :-) ).  Reply to me offline if you're 
interested, I'll box up however many you want and send them out.

If not, I'll probably wind up tossing them in a month or so if nobody 
has any interest.
