You could also buy from rclipos.com
They have the hyperion charger for $140 and shipping is free. They also stock elite lipos, which IMO are very good bang for the buck. 4800mAh 2s elite lipo for $71, 3s is $106, 4s is $136 and 5s is $169. These lipos aren't talked about a lot and i'm not sure why. I have 2 of the 2s elite lipos and so far they are awesome.
Well, good luck with the shopping :)
