That post was from Chad Hill of Chad Hill Propellors, NOT Bronson Hill Propellors. They are both in the same city, are not associated in any way, and are VASTLY different in the quality of work they do. I wouldn't take a prop to CHP on a bet. Too many folks I know have lost speed and RPM's after taking a prop to CHP for labbing. Bronson Hill's service is first rate, all the way. They do many of the race team's props out this way, and come highly recommended.
Bronson may be a bit more expensive than CHP's special, but remember this...WHEN YOU PAY GOOD MONEY FOR FIRST QUALITY, YOU ONLY CRY ONCE!
