Probably not civilian looking enough for your needs but MetalTech sells their own brand as well that are more "toned down" than the OPOR.

I lucked out a few weeks ago and was able to pick up some "seconds" at a discount with welds that didn't meet their high cosmetic standards but far exceeded mine. You might want to inquire with them and other places to see if they have discounted sliders that might meet your budget.
