What's a fair price for DN runners?

What is a fair price for a set of three
1/4" runners 29.75” long with a base length of 20” ,
aluminum stiffeners,
with park brake on the nose runner and
mounting brackets and
carry case?


Used Sarns runners seem to be around $350. Personally, I'd go a little higher if I could find some 36" or 42". New runners $700+. I have a local welder make steel chocks for $50 to $150 depending on the design.
