The only one that I know of is an internal drive that Mitsumi makes. It integrates the card readers into the floppy drive.
Most likely, you are going to have to go with an external floppy drive and a card reader.
Here is the closest thing I could find, but it costs just as much, probably more, than buying seperate pieces. The only thing is that its USB1.1, not 2.0.
