newegg offers the refurbished Hitachi 5GB GST 3K8 Microdrive, model no. HMS361006M5CE00-5, for $10. This $10 mail-in rebate cuts it to $0. With free shipping, that's the lowest total price we've seen for any Microdrive and $13 under the lowest total price we could find for a new unit. This drive runs up to 3600rpm and fits in standard CompactFlash card slots. Deal ends March 13.

A 90-day warranty applies, although it's unclear who supports it.
