pretty funny how everyone thinks that things cost only as much as the hardware. The amount of time I have put into coding rapidfire, as well as what alienX has for that matter, $35 a piece would take a couple years to pay for the development costs of our time. I have estimated that the dev costs for chips I make for mike would be close to $5000, that would be 100hrs @ $50 an hour, and considering in a contract situation would be $125+/hr for engineering talent such as myself $5k would be a steal.
The problem with most the ebay guys is that they don't make high quality chips, just pumping out simple code that takes 2 hrs tops to develop.
You guys do the math and take a look at what Mike charges for high quality kits. Don't worry tho PS3 stuff is on the way from mike as well.
