I've been wanting a plow plane for some time. I looked in E-bay, but the price people pay for some of that stuff is un-believable.
Japan Woodworker has one that is made of Rosewood, has a fence and skate, and it comes with 5 cutters of different widths.
I bought one and it was delivered to my door in a week and the cost including shipping was less than $70. ($65 IIRC).
