Agreed, that's probably the most important part of the equation.
Choosing Reedy electronics makes no difference on the car. That being said, it is rumored they will be launching their own competition level ESC in the upcoming months.
There are plenty of ESC companies which come to mind. Just offhand, the most popular in the US being Novak/Tekin/Hobbywing/LRP with plenty more I haven't listed yet. Since you're new to the sport, getting something your local hobby shop carries is a good idea since they'll be able to help with your setup.
