If someone actually likes the benefits of low resistance, high noise rejection etc. - even if it is just for the peace of mind of using high quality components - you can look into outdoor, in-wall, PV, off-shore, live-event or marine cables for example. You can get the benefits of a heavy duty cable, without paying an arm and a leg for some uncertified DIY project.
I personally like to buy my own C13 cables, so I can get the exact length and connector angle. That just helps cleaning keep things looking tidy.
