I'm all about cheap and effective. I believe that you get what you pay for but there are those "gems" out there. I found one. The poly tac costs about $35 and is 125 lumens, runs off 123 batteries and is super lightweight. I carry my EDC bag with my everywhere and I have one in there, and one mounted on my Mossberg 500. It's still functioning after about 400 shells through it. Waterproof as well. The switch can be depressed for momentary, and of course clicked for constant. Awesome value!
