good charger?

[rcsammy]

hello all, im looking for a good charger if anyone can suggest some
all i need really is:
to be able to run off AC and 12V DC
charge lipo and nimh
and thats about it realy, obviously i want a good quality one to keep lipo's safe, unsure of wether or not i would want a balance charger? it sounds good that it does both at the same time but i have heard they are not as good as a seperate balancer???
anyway i was looking at the Hyperion EOS0606i AC/DC Balance Charger
or this if it is any good as i may be able to save a few ££
