Need assistance regarding charging bases Just bought a system! Quick question- it appears I have 3 black motion plus controllers and 1 stock/OEM white controller. My goal is to get rechargeable packs and charging bases for all. What's my best bet? Do I have to get a different type of charger for the motion plus controllers vs the stock controller? It appears the charging packs are different between the two, but is there a charging base that can charge both types? Ideally, I'd like to have one charging base for all 4 controllers. If they're different, I suppose I can go out and get a 4th motion plus controller and find a charging base for all 4? This is all greek to me, so I appreciate everyone's patience, and help!
