I've got one of these

At 12$, with free shipping, with two ethernet ports and PoE power supply it's the cheapest I could find. Is anyone interested in it? I have one and could easily port OpenWrt to it but before doing it I'm wondering if there are better options. I already have OpenWrt running on mine, but I haven't worked on everything yet in order to get it merged.
