The MRC Super Brain 977 Twin charger does charge 2 of the same or different types of batteries simultaneously. Both the charging unit and the 10 amp power supply are fan cooled. About $96 + shipping at Tower Hobbies.
For Lipos I prefer to use an Imax B5 Li-ion/Li-polymer DC Balance Charger(also does NiCd/NiMh) that I sourced from E-Bay for about $75 shipped. You can use the power supply unit of the 977 for this.
All you need to best charge almost all batteries simultaneously for about $180.
