So, in all, the price on 2 will be about $50-$60. Not cool! So if FIRST has any ties or strings they can pull, that would be great.
There are some white papers on how to build current sensors using OP Amps and either a length of wire, or there is another on just the voltage drop across the fuses, that have to be on the robot anyway. Look in the papers listing above.
