I think most of the cost in quadcopters are in the sensors. I looked for cheap arduino copters and found this http://code.google.com/p/quaduino-ng/wiki/ShoppingList

That's silly. You can buy a complete arduino based flight controller with 3-axis gyro and accelerometer for less than $13. (For the best value I'd recommend the KK2.0 for $29, and for more comprehensive sensors one of the APM based boards, but you get the point.)

Another big cost is replacing and fixing the ones you crash.
