Back when I bought my jalapenos they were only $150 and I chose not to do the upgraded pricing to 7GH/s for $100. The speedup I was referring to was simply a bump in the base model from the original 4.5GH/s specs to what the units I received actually ran at.

Given that the units have almost paid for themselves in one week it's hard to be upset about any lost income. On the other hand I still have only received part of my order and am waiting on multiple 60GH/s units that are just now starting to ship to people who ordered in June 2012. Depending on how long it takes them to get to my order I may have some regrets I didn't just order all jalapenos instead.
