I dont think the 830 will ever be back in stock, Might as well get the 840.
That is really annoying, used to be it was easy to recommend an SSD. A Samsung 830 or OCZ Vertex 4, now the 830 is gone and replaced by a lower quality drive, and the Vertex has gone up in price and is being replaced by the Vector. I have no idea what to suggest to people for SSD.
