Perhaps it is important to note what the margins are on all cables. I worked for a company that merged with a cable reseller (computer cables, but...) The margins were insane. SCSI cables cost the reseller about $1, they were sold for $80. It is a snake oil industry--or at least one that knows it has the market cornered.

And there's plenty of suckers out there, for all sorts of things. Certain types of "medicine" spring to mind.

I am the Doctor, and THIS... is my SPOON!
