Revolectrix PL6 $174.99 from ProgressiveRC.com.
You'll never look back, I promise you.
EDIT: Just noticed that you prefer AC/DC (internal power supply). The PL6 requires a separate power supply. Do a search for "FeatherMerchant Power Supplies" to go with the above charger or you could use a Meanwell power supply like I do. Most of the higher end chargers are going to require a separate power supply.
