  At one hamfest I found 19 used DSDD 3.5"

 Was that $30 for the *lot*? Geez, I've seen these drives go for $30
 *each*. . . 
That _is_ a good price if it was for the lot.  If anyone is looking for
a similar item, I have a box of Sony MP-F11W-72 drives, 720K DSDD 3.5"
floppies for various Tandy boxes, including the Tandy 1000.  One catch: they
don't have a power connector.  They draw power over the 34-pin data cable. 
Typically, floppies have grounds on the odd pins; this one scopes out thusly...

 1     NC (uninstalled jumper at RJ1 (GND) and R1 (?))
 3     NC (uninstalled jumper at RJ3 (GND)) (FAQ claims +5VDC)
 5-11  +5VDC
13-19  GND
29,31  NC (uninstalled jumper at RJ7 (GND)) (FAQ claims +12VDC)
33     NC                                   (FAQ claims +12VDC)

(cf. the Tandy 1000 FAQ - http://www.oldskool.org/~tvdog/1kfaq.html#II.C )

There is a space for a power connector, but it is not installed.  If you feel
like migrating a connector from a dead floppy, it's doable, but for non-Tandy
use, a modified cable might be the better solution.

I got these from the Dayton Hamfest in a "you want one, you take the box"
deal from the local Radio Shack guys that used to have a great booth in 
the white tent in the corner of the flea market.  I will never use more
than one or two of them.  Now's your chance to stock up on bizarre Tandy
drives.
