What I find amazing, is that people will lay down $280 for a $10 gizmo and then complain about the price of synthetic oil or tires etc...
It's actually more than $10 in parts. There's a microchip, a micro controller and a couple caps and transistors. There was a thread over at MBWorld where a guy opened one up and was going to try to repro it with stuff at radioshack. Couldn't be done.
