I know where yuo can get one $8 shipped.
Best new price: what ever shiela quotes you. They have great pricing and the friendship and after sale support is priceless.
Used: I'd pay like $70 if not beat up...
Knivesshipfree.com has their Esee line on closeout. I got a 3 with the Molle back for $84 shipped. They have some for as low as $73, last time I checked.
