This is a great sale for the S3! Never seen these at this price.
It really is an amazing robot, especially at this giveaway price.
I have 3 or 4... lose track after a while!
Ken, the hacker port on top is so great and accessible, it's almost a shame that Andy Lindsay hasn't written a book of hardware experiments to go along with the S3. Along the lines of WAM and Robotics with the BoeBot. So much potential!
