If I was in the market for a new aa flashlight I would go to the local, big name hardware store like Ace and see what they have. Our local Ace has some very nice lights for good prices. For $6 I picked up a keychain light that is splendidly powerful and oh so handy. Go to a name-brand hardware store rather than a Harbor Freight.
I wasn't impressed with the ones I've seen at auto parts stores.
