Other than consistency of construction, "mass produced" cables have NO inherent superiority over "homebrew" cables. With careful selection of parts, proper design and solid construction, it is VERY possible that your "backwoods" attempt at cable building may be much better than what you can buy for 10 times the price.
I would suggest looking at the grade of components ( wire, connectors, solder, etc... ) and the geometries that you're using and go from there. Since you've already got the skills to assemble cables and the tools to do it with, it would be foolish to pay someone else to build you a more expensive product that probably uses inferior parts.
