A method that I find quite economical, is to use a single reamer that allows maybe .0005 to .001" clearance, and ream right through both holes. Then, if there is a preferred side, put a drop of loctite on the pin for that side and glue it in.
Otherwise, you can buy paired reamer sets in .001" over/under for reaming a press fit hole for the pin, and a clearance hole for the easy fitting side.
First you get good, then you get fast. Then grouchiness sets in.
