My charger is a Hyperion EOS0606i AC/DC Balance Charger. It charges Lithium Polymer up to 6s, up to 18 cell nimh, and 7s A123 cells, and 18 cell nicad, all at up to 6 amps. It also comes with a built in balancer and power supply. Price is between 125-150 depending on where you buy it. This may be overkill for your needs, but it is an excellent charger (I own 2 of them) and charges everything.

My batteries I have picked up anywhere from Radioshack (GP 3300 cells only, and they may not have them anymore) to www.promatchracing.com, to maxamps.com (I do not buy lipo from them though), and on my Lipo I only use packs made with enerland cells from Korea (brands are Flightpower, Trackpower, Hyperion, NeuEnergy, Polyquest).

My chargers all came from maxamps.com. I will ask some of the Aussies on my car site where is good to pick up batteries and chargers like I posted in Australia.
