I disagree. Having a charger that can handle present and any future battery needs is a smart purchase. Lots of people in this hobby decide to try some other power source such as electric flight, and it is nice to have a charger on hand that will be able to handle those needs instead of having to purchase other specialized chargers at extra cost. And having a charger that can cycle and give a readout is far more important to maintaining packs than saving a few dollars now. Just my opinion, of course...
