With that budget you're really limiting the quality of the charger if you need a power supply to go along with it or if you want an ac/dc charger and 2 or more ports. This is as close as i can find: ProTek R/C "Prodigy 620 DUO" LiPo/LiFe/NiMH DC Battery Charger (6S/20A/400W x 2). Anything less expensive and you'll be severely limiting the capability of the charger.
