I liked LS-120s because they were IDE and the last generation or two of PC mainboards with a real floppy controller, the controller, or the BIOS, only supported one drive. So with the LS-120, you could have a Phenom II with the same 3.5/5.25 dual-floppy capability as your old 386SX. Bought like four of them in external cases from my university's sale-of-scrap-goods dealer. They're just IDE units with a little adapter board to either USB or some weird propriatery connector.
