its worth it to go with a quality charger imo. too many things can go wrong while charging- and charging is usually the time failure occurs, if failure were to occur.
XTar VP1 is an awesome charger, best one ive used. you can get one for less than $40 if you shop around. among other great features, it can recover over-discharged batts, which can in-and-of itself pay for the charger.
