For what it's worth, I agree with Andy. However, the real message here is not that AM Shifters, purchased before 2007 Kickoff, either are or are not legal for 2007 FRC events. The message is that this is an unresolved question.
We all (teams, volunteers, suppliers, etc.) need an official response from the GDC, on the FIRST Q&A Forum, to settle the question. And soon.
I'm fairly sure that the question has been submitted and that the question and the response will be published together in due course.
EDIT: A related response has been published, saying that
the AndyMark AM-2 shifter would be considered a COTS MECHANISM.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
