Here is the one I use :

It has a good balance between quality, efficiency and price. Of course a 200$ charger that can charge, discharge, condition batteries and all that is better then mine but my definition of "The ideal charger" includes price in it's criterias. For less then 70CAN$ I think that one is great.
greathobbies.com is also a very good retailer. Real fast shipping and cheap too!
