so recently i wanted to buy some apple components output cable for my ipods. went on ebay, and some of the sellers from hong kong had them for $20 (apple has them for $50). i questioned their quality, so i went on to their feedbacks. however, they had 20,000+ feedbacks. i wanted to find feedbacks about these cables for quality assurances. ebay sucks at providing these services. googled it and found this post, which led to toolhaus.org, which provids the exact tools i need.
