I think this thread remains a good example of "ya gets what ya's pays for."
Of course, the popularity of Tekton relies a lot on the idea you are actually getting more than you are paying for, in terms of sound quality relative to other manufacturer's prices. And that's great. But reality can't totally be escaped - and it seems the general fit and finish (from reports I've read) and customer service remains in the "get what you pay for" realm.
Frankly the issues stated here would drive me nuts, and I'm willing to pay more for better service/finish/aesthetics etc.
