When I started R3M3, a month ago, I was using a BS2 for the core intelligence. Aside from price, I enjoyed the simplicity of the Basic Stamp. However, I have since been turned onto the cost-effective-tiny-form-factor PICAXE. So I swapped out the BS2 for a 40X and have used a 14M and an old NES Advantage as it's core controller.
Upcoming upgrades include beefier 36mm BaneBot gearmotors, quadrature encoders, and closed loop data logging.
Scooter Carrying Case The container came on my Lance 50cc scooter. I never put it on and found it stuffed in the back of the closet one day. It has a key lock at the top. So to access the guts, you have to unlock her. It also has a large red relector on the rear.
