If offered a $45 HDMI cable over a $2 one, save your money and go cheap, heck by 3 of the cheap ones incase it breaks while installing it, you will be money ahead and you won't hear the difference EVER.
I hope you don't work with technology in any way. Sure, buy the cheapest cable that meets spec, but remember the first rule of engineering: the vendor is a lying bastard. There's a reason the cheapest cable is the cheapest cable. Paying $45 for a 6-foot HDMI cable is silly. Paying $45 for a 50-foot HDMI cable isn't.
Also, for HDMI specifically, the different numbered specs matter depending on use case. If your doing "4K" video, you'll want the HDMI 1.4 (or above) cable. If you want high color depth for a specific application, you'll want at least 1.3.
Sure, cheap is good, but as always in life, avoid the cheapest crap in the store.
