Did a lot of research, owner opinions included, before deciding on the Sony 34 HE4 Worldwide charger.
Works here and oveseas, is a smart charger, remains cool, can charge 4 AA or AAA or a mix of em.. It comes with 4 NIMH 2500s. I like it very much and consider it a bargain on Amazon where I picked it up at 22.95. Probably lower on ebay.
