Microdrive-like device using SD cards?

Hi,

     Just an interesting question here. I have the Microdrive card that uses 
CF cards, and love it! But I kind of get the impression that CF cards really 
aren't that popular any more. For one thing, they're a lot bigger than some 
of the modern cards out there. Please let me know if I'm wrong about this! 
Anyway, we have several devices in our home that use SD cards. So I was 
wondering, does an equivalent to the Microdrive exist, but that uses SD 
cards? In the best of all possible worlds, it would use something like a FAT 
or FAT32 filesystem with .dsk or similar images, and let you swap, copy, 
etc. from your PC, not having to use CiderPress.
Thanks!
Jayson
