Hard to go wrong, most of the ~$50 1xAA lights that you will find discussed here a lot are really incredible.
My advise: Pick the one with the interface and modes you want most. Some people prefer simpler interfaces with less modes, others want more complex options on the table, or a balance somewhere in-between. Don't worry too much about lumen ratings, if it has a modern Cree emitter it's going to make ordinary full size flashlights look like they belong in the kids department. The difference between a "100" and "200" lumen rating is enough to notice if you compare side by side, but won't make much if any difference in practical use, as pretty much all 1xAA cree lights are going to have *similar* beam patterns.
