Nah after all to conclude, it is only how some company plays a game. Difference is that Sullins will give you higher price of the connectors but lower tooling fee. In China you got opposite so at the end you have the same price in terms of low quantity numbers we have here.
@Majsta, was this not resolved a while ago already? (I had the impression Kipper2k found a good source some time ago.) Have you received any samples from the chosen supplier to determine quality?
