I bought this when it first came out and found it of limited use in my first model.  However , when used with the sort of model it was designed for it works well.  I enjoy supporting this sort of endevour and consider the thirty five bucks to be money well spent.  

Completely agree with you! The video Jonathan did on EweT00b is quite compelling....
