Reviews of the shuttle board are at best, not very good. I wouldn't touch it or any other shuttle board as they all aren't very stable compared to others. Soltek I've used and it doesn't impress me, its an ok board. I'd get Abit or Epox, its a toss up, both great boards.
If I were to get another KT266A it would be Abit or Asus again. FIC AN11 is nice too, I'd have to see the price on it.
