Hagan, James Duffs arms are $750 or so shipped… yeah still a lot of money but they are pure beef and eye candy. I really like the way they look.
Yeah you're right. I thought they were more. Its just 2" diameter 1/4" thick tubing. And I believe my heim joint is actually bigger. But, they are bolt on, have caster built into them, and are angled for tire clearance.

Axle looks great!
