(The big reason, that I liked the Scott Creek, was the notched ladder, that the plunger uses. I prefer that, over then Brent yolk set up.)
I have both of these extruders-the clevis pin on the brent takes getting used to and now Brent makes a notched ladder as well-I would go that route today if I bought one.I think after using the ladder for 35 years I tend to favor them. I am a bit different as well as I use the heck out of this tool almost daily and the Brents are so heavy duty they have been issue free.Now that Brent makes a ladder its a no brainer. I would also consider using another brands hollow forms as you can trade them around-al long as its a round 4 inch or sqaure model-meaning sq is sq and round is round.
My Scott creek has had about every modification you can think as it was an orginal model from the orginal inventor(1970s). The cap was before the pin model of today and its now a Brent cap after redoing it. The ladder wore out and the handle was beefed up. I have gone thru 2 plungers discs and the barrel is now 1/8 larger than it once was.The brent has survived with zero issues.Most will not push that much work thru one so it really comes down to way works for you.
Just make sure it holds at least 10#s of clay
Stainless is great but I never and I mean never have seen rust on my porcelain from my rusty extruders and thats all we use in them-(Porcelain). The barrels are rusting-but contamination is of ZERO issue.
