Too expensive for the gains in my opinion. I'm in the process of sandblasting smooth the inside of mine. I purchased a sandblaster from harbor freight for $70!

to add to the original question..

anyone have concerns about the secondary injector ports when extrude honing...

How are you doing that??

Are you using large very abrasive media for long periods of time?

and adjusting the sprayer periodically

Why would there be unless they purposely ran the media through the port?
