Again with Imax B6AC, Where to get replacement?

No, this is not a good question for the forum but something I would like to know, it would be great help! Anyway... I have found the problem with the fake one I have now. There is a weak power supply and think it would take to much to fix. But I want to get the REAL one or something like the B6AC. I will never get my project done with out one. Does anybody have one and know where they got it? Could you provide the link, especially if it was amazon or ebay. That would simply be great. Thank you!
