I can't say for sure that there aren't frauds, but the price has plummeted. I've seen genuine working A9s, both on ebay and from other non-maintream dealers, at $60 plenty of times. So no, chances are its genuine.
They're also at DX for $50. And they claim that they have genuine A9. Besides even official (and "more expensive") dealers reduced ther prices for all Tiablo products (except A1) they have in stock (looks like clearance sale).
