Price is relative. I have done partial harnesses and enjoyed doing them but with a 10 and 4 year old in the mix and almost no time to work on the car these days un-interrupted every 5 minutes, <$500 for a high-quality printed sleeve kit just works. I want this to be done once, done right, and drive the car as much as possible.
And I don't know about you but when I do get free time to work on the car it is also combined with time to drink some beers. And having printed wires and a neat kit is some added insurance for that scenario IMO.
