The downside of this is with no balancer, you won't have good results with any of the less expensive lipos like Turnigy's or Zippys from HobbyCity. You'll have to buy one of the premuim brands like mentioned. It doesn't hurt a lipo to balance it and it takes no additional charging time either. All it takes is connecting a 2nd set of wires. Some of the chargers mentioned are DC only and will need a separate power supply.

I took your "won't break the bank" literally. What do you want to spend on a charger? What do you intend to charge, there's a big diff in charging 2S and charging 4S lipos as far as charger is concerned. And btw, chargers that are lipo only are usually for airplanes and not really a good choice for surface RC use.
