Which ever charger you get....make sure it charges cells 'individually'! Otherwise you will have issues if one battery has more of a charge then then 2nd battery, or say if one battery is older.
Be careful with the Sanyo chargers, if its the newer 'MQN06' model it only charges in pairs, the older MQN05 apparently had individual channels. I have not heard about the apple charger, so I can't comment.
If it was me...I'd buy the Maha C9000 Wizard one charger ( I own two now!), best charger for AA & AAA ever made IMHO. You can pick this up for less than $50 and I've seen specials here in Canada for $82 which includes (8) Imedion AA batteries.
You can always get deals on the eneloops ...but the charger quality should never be sacrificed!
