I use my Hobbico Quick Field Charger MkII in combination with my Electrifly Equinox balancing module:

The Hobbico Quick Field Charger Mk II will charge 1-8 cell NiCd and 1-8 cell NiMH batteries for receivers, transmitters, or power packs. It will also charge 1-3 cell LiPo batteries. The charger can autodetect the number of cells, can charge two batteries simultaneously, and the charge rate can be set independantly for each battery.

Add in the Equinox Balancer and you can charge LiPo batteries with balanced charging jacks. If you have two of the Equinox modules, you can charge two balanced LiPo packs at the same time from the Quick Field Charger MkII.

I have an MRC Super Brain 989 charger that I leave at home for trickle charging, cycling, and what not. The Hobbico QFC MkII and the Equinox combine to handle about 95% of my regular charging needs and I find the combination of the two very handy.
