Marketing of PCI Express SSDs has always been somewhat tricky as the fine balance between performance and value wasn't much of a balance at all; performance being the obvious strongpoint of these cards. The difficulty in manufacturing a consumer directed PCIe SSD, that can promise value, has most likely been the reason all haven't jumped aboard the PCI Express.
