Which Charger?

[tjpMT2]

I'm Looking for a charger to charge my Receiver pack and transmitter pack for my 'smelly nitro thing' I'm a complete noob at leccy stuff but at the moment i need it to charge NiCD's and NiMH's but for the 2008 season I'm hoping to be running Li-Po's. It will also need to be able to charge a 12V battery. Bonus's would be discharging and cycling (for the NiCD/NiMH's) and ideally it would be 12V and mains. I'm not sure how important Li-Po balancing is so would that be needed? Would be good if it was a good make for re-sale!

Thanks in advanced,

Toby
