I read over their site already about a week ago as I am planning on a split this spring / summer myself. Seems like a lot of money for something that seems so simple. I guess if you have no time or are not so good with tools it would be worth it. The waterjet thing.... meh, does it really matter that much? I doubt it. Honestly I am looking forward to making out material due to my smaller feet. I make even make two passes with the saw just b/c of this.
Also, speaking of split boards.... Timmy you still have that Slackcountry lying around?
