If you think you are going to stay in RC for a while you should really think about getting a DC only charger. When limiting yourself to AC/DC chargers you pay a premium for the sub-par AC capability compared to an external power supply. If you are looking for a dual channel charger that is relatively cheap, I recommend the Hitec Ultima X2:

With Tower coupon you can get it down to around $125.

For the power supply, see the following page on how you can use a high powered server one for around $25:
