Here is the one I was talking about. http://www.amazon.com/RENOGY-Monocry...gy+solar+panel
It looks like the Harbor Freight is a bit of a kit, but I'm not sure if what they are calling a voltage regulator is the same thing as the charge controller, but probably. Most of the stuff I've been reading says that while a 10A charge controller will work, it leaves you limited ability to upgrade. For what you're doing, 10A may be okay (I'm not sure and I recommend you check on that).
Here is the Renology "kit" that comes with the charge controller. http://www.amazon.com/Renogy-100W-Mo...gy+solar+panel
The advantage to the Harbor freight is that it sounds like the charge controller comes with multiple charge ports built-in, which would be closer to plug and play if you don't want to jump in with both feet to build a system.
