I highly recommend just building a Thin-ITX router. I have a post of how I built mine here:

I paid too much for parts. You can easily construct one of these for under $200. I'm sick of ARM and needing a different image per device.

AVOID the ClearFog and BPI-R1:

I cannot recommend either of them (although if I had to, the BPI-R1 is better than the ClearFog. Just don't expect it to be stable)
