Don't forget about aluminum, I have been using aluminum camlocks for the past 3 years with great success. Got them from proflowdynamics.com.
good luck with your up-grade
p.s. what's next, a new SS braid : )
Outside of the obviously higher cost and therefore likely larger margins, I'm curious why Proflowdynamics.com catagorizes the SS camlocks as "Home Brew" camlocks and the AL models not?
Honestly if I'd known about them beforehand, I would have tried the AL version. They are a lot less money and if they work well, then that's the way to go.
I bought mine from a LHBS Adventures in Homebrewing in MI and they only carried the SS version.
