What would seem reasonable to me is that there be a lower limit, maybe $5 or $10 dollars, under which you could buy electronics parts from anybody.

It's too bad if we can't use these Piher pots (for example). They are less than $3 each and make great continuous rotation sensors. I have not yet found anything similar from the listed suppliers.

As I understand it, we've got only those 3 suppliers. But, I like your idea. I think we should propose it to FIRST (for at least 2005 if not this season).

Anyone up for making the suggestion? Nice and pretty now, nothing like, "you guys really blew it on this 3 supplier's only rule, you can make it up to us by getting half a brain and ..." Remember, we want them to agree with us!
