I've seen Ed's cables from kindkables and they are really nicely constructed. No idea on the tecnec stuff, but it could be a good cable, the price seems very good. But remember it's $77 for the pair vs $23 apiece, plus some of the more expensive ones probably use upgraded neutrik connectors. You should also double-check exactly what starquad the tecnec's are using. There's the regular starquad and a smaller, low-profile starquad that isn't quite as nice. You can look up the exact part numbers for the different starquads on canare's website.
