I can't say enough about the 8RDA+/AU11 boards. They are fantastic overclockers, value priced, and offer a fair amount of features. I totally love mine and so does my Barton 2500+
I love my EPOX 8KHA+, I've been pondering getting a 8RDA+, I'm just not sure if I want to make the jump with NVidia's Linux support not quite there yet for nforce2 boards.
