I haven't heard of any... and trust me, I looked. For the machine that I built for my dad, I ended up getting a Gigabyte GA7ZM first, but had a weird problem where it wouldn't boot sometimes. Eventually picked up a MSI K7TM (6340) - this was much more stable and worked great (even on a wimpy 145W PSU). Currently running a Duron 600 on it. The MSI is my recommendation for best micro-atx Socket A board out there (they seem to be making the best Socket A boards, period...)
(I currently have the Gigabyte board in a different case now running a Tbird 700. It works fine - I think maybe it was getting a short in the original micro-atx case that I put it in. Still like the MSI board better, though...)
