Don't let me discourage you from getting high-quality wire!
It seems to be a problem with many people starting out, that they try to build their first cable with expensive top-shelf parts, but they haven't got the experience yet to do a good job, so they either ruin things or psyche themselves out of it. Far better to build a bunch of cables on the cheap, learn the craft, and work your way up. You'll end with more cables than you can use, but there are always other people who want cables.
It's the good guys like you and Fraggler who keep the craft going
