Depends what your purchasing factors are. Is cost your main sale point or is functionality like wi-fi options something you care for?

I recommend Juicebox if you want everything in one package: https://www.amazon.com/JuiceBox-WiFi-equipped-Electric-Vehicle-Charging/dp/B00UB9R4KO/ref=sr_1_3?ie=UTF8&qid=1495805823&sr=8-3&keywords=juicebox+evse
