I have recently purchased 5 of the River Rock lanterns available only at Target. This thing rocks. Waterproof, indestructible - I have thrown one of them against the floor 3 or 4 times as a test - no damage. Bright - and should get at least 8 hours of light off of 4 AA batteries. It's only $19.99. Not all target stores carry them, but this one is absoutely the best for the money.
