My rule of thumb is that my time is valued at $100 per hour. Many years ago I used to make all of my computer cables. That entailed getting the cable and connectors and then soldering maybe up to 100 connections, depending on the type of cable. As time went by I found that it was easier, faster, and seemed cheaper to just buy them off-the-shelf.
