Where I buy my hardwood, there is no difference in price between plain maple and tiger maple. A 1 x 6 S4S maple board would sell for $2.31 a lineal foot or $4.62 per board foot. The lumber supplier supplies mostly to contractors and they tend to stay away from the curly maple as it doesn't blend in as well in trim and such in houses. I can usually hand pick all the curly boards I want for no extra charge.
