Which charger to buy

[Mash Potato]

All,

I'm after some advice. I'm a bit out of touch with the latest chargers and technology etc. I have an two old Bantam BC6 chargers which have done me well. But I'd like one charger that can charge up two batteries at once, at more than 5A (current BC6 limit). I have quite a selection of LIPO batteries that will need charging, some 1 cell, 2 cell and 4 cell batteries. Open to suggestions as to what to go for as there seems a lot of choice. They are quite pricy, so peoples own experiences with their own chargers would be appreciated, as I really don't want to buy the wrong one.
