can i get some advice on buying USED sliders, besides smoothness/straightness/sturdiness?
is there a certain technique you guys do for checking smoothness/straightness/sturdiness?
and checking if holes are drilled right?
its a IGUS 40 inch rail system

and a Giotto pan/tilt head.

any tips and tricks?!
