I've been using centro battery as backup. I charge them in centro battery charger (bought batteries and charger from Ebay, less then $20 for 2 batteries and charger) I have 2 PRE batteries as well (they too charge in charger). I went as far as cancling my Touch Stone order, $70 (yes there are deals for $50 or $60) but I found I just want charged batteries to USE PRE, not impress anyone how I charged them. I'm enjoying all the toys PRE has to offer and I have had n0 issues with batteries.
