Hey good choise on the EPoX. I have been running an 8KHA+ for about 6 months now and I love it!! EPoX is deffiniatly on my short list for motherboards.
I can hartely reccomend
http://www.newegg.com as well as
http://www.kdcomputers.com. I have dealt with both before in the past and their service, time from order placed untill it is sitting on my door, and price (newegg is slightly better) are excelent. Be sure to check the "refurbished" section at newegg, often you can find some real steals there!!
