If you want to stick to 4xAA, check out the vinhnguyen54 thread in the CPF custom flashlight builders and modders section. I just got a Sunwayman D40A neutral from him that is putting out over 1400 lumens on turbo, I have a ea4w and it doesn't blow it out of the water-but it's so much nicer. I also got a Sunwayman T45C modded by him that is 2x18650 but is the same "feel" as the ea4 but only slightly longer and can really "throw" for its size. Both were right around the $100 price range.
