AC is shrockworks sliders. I have a set that I picked up used. Worked out great.
If you have welding skills...sure, get the trail gear sliders and fabricate the bolt on mounts...or have someone else do it. It isn't overly complicated, but it is tedious getting all angles perfectly 90 degrees and bolt holes lining up right. A price can be paid as a nice substitute for someone else having figured out the jigs for reliable placement.
To get the function of a slider, really, you can get by with a plain single tube like the Calmini ones. Additional bends, tubes, kick outs, plating, etc is mostly aesthetics (OK, a kick out can be argued as useful). Those features just add cost, operations (more bends, cutting, welding), and complexity.
