Don't leave MSI out in the cold, now producing some very high quality M/boards.

Asus & Abit are also excellent manufacturers of quality m/boards but seem to be less adventurous these days with their new products. (but that may be me being cynical <img border="0" alt="[Laugh]" title="" src="graemlins/laugh.gif" /> )
Good luck in your hunt.
