Lexar 12-in-1 USB2 Card Reader
 

This is the current generation of Lexar card reader and it features a plethora of card support. You can read CompactFlash (types 1 and 2), Smart Media, Memory Stick, Memory Stick Pro, MultiMediaCard, xD-Picture Card (Type M and H), SD Card, SDHC, MicroDrive, MS Duo, MS PRO Duo, miniSD, and RS MMC. That's pretty much the available options on the market right now. They still include support for Smart Media which is so outdated.
