Check the "General Electric" section for info on how to get a dirt cheap 47A power supply.

The iCharger 106B+ can be had for about $100 and can handle 6S, 10A, and 250W total power, which makes it quite capable even for being the entry level iCharger. If you can afford to spend a little more look into one of the more powerful models, but any in the iCharger line is solid.
