I don't know what "your local guy" would charge or what kind of warranty would be provided (labor only most likely), but this is straight from the Firm Feel website; "cases are machined for roller bearing sector supports and worm gear assemblies are resized, then the box is fitted with Firm Feel's exclusive reaction springs".
Yeah, just a simple job for your local guy.
In my dealings with, and all my friends dealings with Dick Ross, he's proven himself to be a no bullshit, straight shooter kind of guy that I would do business with again. And even if a "rebuild kit" is offered (from Dick Ross at Firm Feel), why would I want to take a job this specialized to someone who has not learned all the little "tricks" doing it year after year, day in and day out.
