We got ours in the mail from Analog today. The PCB actually comes on a 20 pin chip socket.

Thank goodness they increased the electronics budget to $300. We were looking at creative book-keeping methods to get our budget into the $200 and include all of our encoders, potentiometers, limit switches, and the yaw rate sensor as well.

On the ADXRS300EB, there is an interpretation question. The cost to buy one from future-active (the only available legal supplier) is $100.50. The cost to buy 2 is $90.45 each, and the cost to buy 5+ is $77.05 each. (incidentally, the cost to buy from analog devices is $50, but you cannot use this for book-keeping purposes.)
Which number are you supposed to use in the cost accounting? I'm pretty sure that FIRST has given some latitude, especially for raw materials. For instance, if you buy a 4'x8' sheet of aluminum and only use 4'x4', you can book-keep the price at the 4'x8' rate (ie the 4'x4' section is 50% of the cost of the 4'x8' sheet).
So, an argument could be made that you can use $77.05 in your cost accounting for the ADXRS300EB and that therefore it is a legal part.
We're using the ADXRS150EB, so I'm not concerned about this argument. However, if the ADXRS300EB were critical in your design, I would consider asking the question on the Q&A system.
