Look at this website..or one of the others that come up when you google "heart pine engineered flooring"

snausages Heart Pine flooring prices are going to be all over the place for several reasons. The grade of flooring, lengths, age, source, and story behind the floor will all play into the pricing. You can afford the flooring if you find a direct source and not just a reseller. We resaw antique heart pine beams into planks and then run them into flooring whenever needed. Going the engineered route to try and go cheaper may not be the best idea unless absolutely necessary. If you have any questions shoot me an email. joel@eutree.com

thanks very much for the info!
