[New Lightning]

Here is what has, IMHO, has been implied with some of the posts in this thread but not actually said. Having a shortage or a lack of availability of parts is part of the real world in multiple facets. First suppliers must try and predict the quantity that will be wanted and then how much in terms or raw materials and wholesale product they need to buy. Second if what you want is not available then this actually presents you with the opportunity to find a similar product that is comparable just from a different source. If no such product is available then coming up with a new solution that doesn't rely on the missing product is part of the challenge of FIRST and having a limited time frame in which to build your robot.
