Last time I had kingpins honed at the machine shop it was quite cheap. I forget the exact price, but it was certainly a "no brainer" decision. And I have my own general machine shop, even have plenty of adjustable reamers, some with pilots, and like to do all I can myself. But when someone else can do a better job faster for little money I'll go for the better results.
Did you check the price at a few of your local automotive machine shops?
