I had a look at this trying to convince myself I need it, as I like these kinda things but considering the price, and then the instructions being pretty vague, and then having to make a template up to build something out of scrap wood or whatever, sorry but if I am laying down $370ish (ie 3 times the price of the MD2 dyno which didn't need me to make a template up or home fabricate anything) I want to see my $$ worth.
