Johnny sorry to be the bearer of bad news, but you are very late to the game. Not only have the BFL products not been released, they have been delayed over 6 months. The chips havent even all yet been made, just a test wafer which hasnt even been fully tested, let alone assembled into a working prototype, let alone manufactured into a product ready to ship - and their customer support is non-existent. IF they are able to get all chips working correctly, IF they are able to build working prototypes and final builds, THEN maybe they will start shipping in a month or two.

BUT if you order now, you have 19,000 orders ahead of you and by the time you get it in September-October the network difficulty will be so high that it will take at least 8-12+ months just to break even on your investment. By 2014 the profit per GH will be low - very low. Its maybe worth it if you dont mind a high risk long term investment - MAYBE.

If you are bullish on BTC, buy BTC with the $30k - because you will start making $ immediately - not 12+ months from now.
