JeffMc.. if you think you might someday move into the 18650 sized rechargables with LiION or LiFePO4 chemistry, you might look at a smart charger with that ability up front... in either case be sure to get a charger with 12v cigarette plug capability...I've been extremely happy with the Sanyo/Panasonic AA and AAA Eneloops... make sure they are produced in Japan...
