In case anyone needs a floppy drive - we've got a rather large stack at the office (used). Free for postage.
I'm pretty sure all of them work with DD as well - but there may be limitations to the controllers on somewhat modern boards. Had to find out the hard way when a P4/Prescott machine wouldn't use the second drive...
Of course, recent boards ceased to support floppies at all, so get a USB drive.
