Yay - another thread questioning Nengun
Please use the search function before posting yet another thread on this topic.
Nenguns service speaks for itself and considering the fact that Apexi japan has had no stock of several items, namely Power FC's for ECR33's, im not surprised in the slightest that you are having delays.
Rather than posting your concerns here, why not pm Brent or shoot him an email? Im sure he will be more than happy to answer your questions.
