Unless you are a complete klutz with a soldering iron, it ain't THAT hard to make them for yourself and save a FORTUNE.
Practice a few times with old, bust up cables and connectors, get a feel for how the solder runs, how to clamp everything together so you aren't struggling to do three hands work with two, and you'll probably never need to buy a ready-made cable again...
