I included a few examples; I had trouble finding anything in your price range. I have used ecs and jetway motherboards before, but you will probably prefer Intel. I can't guarantee driver compatability, but if these boards had any vista or windows drivers, they should work fine with windows 8. Ecs has a pretty good website; here's a link for the above board: http://www.ecsusa.com/ECSWebSite/Product/Product_Detail.aspx?DetailID=1306&CategoryID=1&DetailName=Feature&MenuID=16&LanID=9. This ecs g41-m7 has windows 7 drivers available, so it will work with windows 8.
