motherboard for FX-51

I have an AMD Athlon FX51 CPU. I have been using an Asus SK8V motherboard
which I have really liked, but after a recent thunderstorm my ethernet card
seems to have taken a hit. Now, I am having to use the USB port for my
cable internet service. Just out of curiosity, I have been surfing around
looking for a replacement motherboard. Not much available. Anyone else
have the FX51? If so, do you have a good web site to buy older motherboards
for that particular CPU? Or do you know of any other options? At present,
I do not plan to upgrade my cpu, but I will get the itch sooner or later...
