Dan, Here's a trick you can try. Find one of the Ebay sellers who sell the re-man H&Rs and send him a note asking him how tight they hold the tolerances to, mention that you are curious about the quality control in the process of machining.
One who knows his product can tell you and most should not get bitchy or offended.
