>>2765726Depends what "cheap" is to you. The Streamlight ProTac is the cheapest thing I'd buy, not super bright compared to the rechargeable Chinesium brands but it's a durable reliable light that runs on either a single AA or a single CR123 and costs $45. I replaced mine for everyday use with a rechargeable Fenix that cost twice as much and is four times the brightness but I keep the Streamlight in my truck because I know that it's gonna be there and gonna work in a pinch and that I can easily get batteries for it anywhere if I have to.
