I have 4 of these (Amaran 500 LED) and they are fantastic. http://www.amazon.com/Aputure-Amaran-AL-528W-LED-Light/dp/B00CBAVWG8
I get great front lighting for 1 person for one of these, so add a second for the other person, and one or two for back lights, and you get a great look. If you look harder, you can find them all for pretty cheap, about $140 each for me. I've used them for a few months now and they take a beating pretty well.
If you want to see the lights in action, you can see what it looks like here.https://www.youtube.com/watch?v=HGvQj0uEnlc&list=PLHlCjeHVmwFHdAQT2YxxJR...
All lights are on about 75% power. F/4, 1/60sec, iso 640.
