I'm liking the Lumintop SD4A right now. (M4D M4X has code that meets your price point.)
It gets some criticism for not taking 18650s or 26650s, but it does take 4xAA, which meets your criteria, and 1xD. I got it for my dad who didn't want to mess with Li-Ion and it is working great. The two button UI makes it simple to change between the basic modes.
