Best price I've found is on alternateforce.com
Great knife, won't let you down. Only complaints I've heard about it are that the blade develops blade play over time if you open the knife with a wrist flick. Use your thumb to open it and you won't have any problems.
Also the wingwalk inserts will loosen up and get sticky if the knife is continuousy submerged in water for more than 24 hours.
