I wonder why they made that distinction. Is it too much of an advantage to have a drop-in replacement motor or controller ready to go?

I could see the first task for a student in the pit being to crimp some connectors onto a set of spare motors and controllers, ready to go.

In fact... *writes that down*

As for the poll, I voted for Talon SRX since it seems to offer quite a lot of potential advantages for the fairly minimal extra cost. Virtually every one of our robot failures last year, both on our practice field and unfortunately during our first regional, was some combination of our software addressing the incorrect PWM or DIO, the encoder wired incorrectly, read incorrectly, software values set/reset incorrectly, motors trying to run the forklift past the edge (e.g. we didn't have time to wire in a hard limit switch), etc. If we thought to use the limit switch and encoder functionality in the Talon SRX, and communicate over CAN instead of PWMs and DIOs, our code (and failure modes) could have been much simpler.
