I'm no fancy flashlight guy, but I carry the coast g19 daily.
For what I need a flashlight for, it just works. Takes a single AAA. Doesn't throw far. But has very even light which is great for looking in engine bays or whatever crevice I need.
Plus, it's only $10. I ended up buying a half dozen and tossed them everywhere around the house and in my various bags I carry.
