That shield was actually the one I was looking at getting. I ended up starting a new post, just since I'm working on a different topic now with servos and shields instead of just main microcontrollers.

I'm looking at the legs now, and from a couple replies in my other post, and as fkeel stated, I don't need the shield at all, just eases the process a little. My only concern is powering the servos and I understand the arduino won't do a very good job doing that, much less with 12 servos. I would have to re-route the power to the battery instead of the arduino, would I have to do that with the shield as well? If so, I may not get a sheild if I'm going to have to re-wire everything anyway. Second question is on the servos I picked out. I picked them out because they have the fastest speed for the highest torque and the lightest weight that I can tell. Just curious if anyone had an opinion on these or had another servo they preferred using.
Here are the supplies I'm looking at:
Shield: Error, Electronic & Electronics Components Depot United States
Servo Possibilities:
37G EXI Digital Servo D122F EXI-Servo-D122F
Solar Servo D222 0.17@6.0v Digital 37g
Pan and Tilt Kit: http://www.robotshop.com/lynxmotion-pan-and-tilt-kit-aluminium-1.html
This is all in the second post as well, but I'll be monitoring both.
