So I found someone selling a new in the box Incra Ultra Jig (24 inch) for $150. It originally retailed for $250. I don't think it's made anymore, but it looks like the cat's meow for dovetails and box joints. I haven't done any of this type of joinery but would like to. Is this a good deal and something I should jump on? Not a lot of info about it via Google so I thought I'd try you guys.
