Alternative for Powerex MH-C800S battery charger??? SOFT charging needed.

I am just wondering whether there is any alternative for Powerex MH-C800S AA (AAA) battery charger. I had two units in the last 4-5 years. Both of them are dead.
I like them as a charger when they work. Unfortunately, it turns out they all fail within 1-2 years if you use them (all the time) as a professional photographer.

I would like to have a charger which allows me to charge battery in "soft" charge mode to make sue my batteries last long and it lasts more than 2 years...

THANKS SO MUCH!

I picked up an Opus C-2000 a while back and so far it has worked really well. Charges each individual cell, has modes to test capacity, refresh, displays voltage, etc. It also can charge as low as 200mAh per hour, although I've read that you should use 400 as a minimum. Wasn't that expensive either, although it can only do 4 batteries at a time.

Thanks so much!!!
