If you put either one of those speed controllers with two drills, you will blow them. Drills motors will happily draw more than 10A in the arena. My advice especially for someone starting out is to buy the electronize controllers. Rough, rugged and perfect for someone starting out.
I would tend to agree with this, The 10A Sabertooth will hold out until you get a significant stall current for a while.

I reckon you have the option of the electronize or the robot power scorpion XL or XXL or the sabertooth 25A. Just remember for the electronize you will need a mixer if there isn't one built into the tx handset
