Depending on where in the country you are, both Airsoft Parts Canada (Eastern Canada) and I (Western Canada) carry inexpensive smart chargers as well as most other retailers here. You can also pick up chargers at any RC shop. Wall chargers are notorious for burning up batteries as they don't turn off or trickle charge once the battery is finished charging.
