I had a cheap one from amazon with all the useless features and flashing lights and bs. It was OK but I used it enough that I decided to get a decent one.
I bought this:

simple and works very well. I like it so far and have used it a bunch. The flashlight comes off and makes a pretty good stand alone mini light as well. Battery life isnt super long on the highest setting. maybe a half hour, but not sure. The medium setting is plenty bright and lasts plenty long
