Indra and Varidig Sextet are very expensive cables vis a vis the competition. Are they worth the expense? That's strictly up to the buyer. However, they are arguably the best products available; this has been confirmed by both hobbyists and professional reviewers. The existing problem with both is that they are so highly resolving, many systems are not suitable for their use. Many lesser priced cables will outperform Indra and Sextet in some systems for that reason.
Cheap to make? It's a little known fact that the most expensive wire used in any power cord, speaker cable, or interconnect rarely exceeds $10/meter. So in that regard Stealth and every other cable is cheap to make.
Overrated and overpriced? Strictly a buyer's decision. If the user derives value from the purchase, that's all that matters.
