Why restrict yourself to Sanyo chargers, when there are so many others which are very capable and provide a lot of useful features? Eneloops don't require any special treatment beyond what any other NiMH cells need, so any NiMH charger can be used.
I've used a couple of Maha MH C-9000 chargers for years and find them to suit my needs, but there are a number of others that have similar features and probably do the job about as well.
