If you want to be able to do nimh packs too i would go with the duratrax ice. I actually have both and prefer the astroflight when doing lipo packs because it charges a little quicker (doesn't lower amps after reaching full voltage, it does a pulse instead and completes about 10min faster)
Both chargers are about the same price. You will also have to get a powersupply if you dont already have one.
