The cheaper the better, and I'm not afraid to solder.
How about a SheevaPlug[1]? Very small, has a USB port, ethernet, and an SD slot, and is $100. 512 MB and 512 MB flash is probably overkill for you, but at this price, it's just gravy. Granted it is not DC, but since it is the size of a power brick it shouldn't matter! I'm sure you could drive the thing with DC if you put your mind to it. I own two of these and they are very capable little units. They ship with Ubuntu 9.04 (but not the long-term edition), and since Ubuntu 10.04's ARM distro won't be compatible with this processor, most folks are moving to debian stable.
