It's the construction that matters, not the conductors!

You can get burned buying cheap cable, but only because it is poorly made. Cold solder joints, inflexible connector ends, shorts or breaks along the conductors and reflections can all impair the presence of the signal. A well made - strike that - properly made cable, even if it's $5, will perform perfectly transmitting digital material.
In the analog world, signal attenuation (lessening) and can occur as cable distance increases, due to reflections, RF noise, and the like. But the sending and receiving circuits should properly deal with that, although cable composition can improve things a bit. You should see what the guys who install cell towers pay for RF antenna cables!
I personally use the cheapest 'sturdy' cables I can find for both my analog and digital needs. While I fear the possibility of online cables being the rejects of ETDR testing, paying more than $5 plus $2 per foot for home audio/video cabling is sheer insanity (double that for a 100%, lifetime, no-questions-asked, door-to-door warranty).
Of course, there are economic benefits to those more expensive cables, as PT Barnum foretold. It keeps the GDP a smidge higher!
