I've heard great things about both chargers but judging by price I assume the ICE is the "better" since its 129 for the charger alone, the 989 is 139 with a 10A power supply. So 139 - about 30 or 40 bucks makes it a 100 dollar charger.
I forgot to mention earlier that I have been leaving toward the 989 simply because of the included power supply. But I'm still interested in hearing on what people think of these chargers and which one is the better buy.
