I highly reccomend the ice charger. Great value;Tower hobbies is currently running a special on them. Personally, I bring 3 chargers, break in machine, and several discharge trays, but it is a little overboard. I would try to get two chargers, with at least one having discharge/motor run in features. Your second charger can be a cheaper model, such as the puslar sport or millenium pro.
