OK @mceljo - if you do not want to take the time and try them, then it will be hard to determine if the inexpensive ones will work just fine or not… and also will be hard to understand what the $200 cables would do that the cheaper ones would not do.
Someone needs to mess with building them, either you pay someone, or you build them yourself.
Obviously I like the convenience of being able to build them in the specific length, on a Sunday when the stores are closed.
