I just purchased a Cycleops Magneto online for 200 (including the block) and the shipping was free. It is a 2006 which is why it was cheaper (they are now pushing the 2007 model) The cheapest places tend to be online. I looked at bike shops and they were all way more expensive...around 70 bucks more expensive and when you are trying to cut costs 70 bucks makes a huge difference. Good Luck!
