"BYO all-terrain robot" book, motor question

Hi there,
I want to start my first journey into robotics with Brad Graham's book. Haven't ordered it yet, but want to know if it would be wise to start
shopping for the motors, as I spotted this on eBay:

What do you think?
Thanks in advance for your advice,
-Jorge

Buy the book first. You might save yourself sometime and hassle. I always try to learn from other peoples mistakes before I make my own.
