replacing the Sony Cybershot DSC H20

[chesterc]

hope to get some assistance. my wife does dog training indoors and outdoors out to about 40 to 50 ft, her current camera she uses for her videos is the Sony Cybershot DSC H20 the battery door wont stay shut so she wants a new one for Christmas, i looked around for a new one, can't find them, so we looked at the Sony Cybershot DSCH 300 which is supposed to replace the old one, was going to order it, but stopped as soon as i saw it take AA batteries, my wife does not want this camera , she like's the single battery pack like her old Sony. any cameras out there that use battery packs rather than the AA's in the same price range. and will do as good videos as her old DSC H20

thanks
