White wood

I'm looking for a wood that's very white. Holly would work perfectly, unfortunately I can't seem to find a place where I can get pieces bigger than pen blanks that doesn't cost $50 a board foot. I've found lots of spalted holly over at wood barter, but I don't want spalted. I'm not aware of any other woods that show almost no grain and are very white. FYI, I'm planning on making a turret from the Portal games and want to avoid using any paint or stains.

Does anyone know where to get holly or something similarly white and bland at a reasonable price?
