That is how you would mount it. I also highly recommend Fenix's L2D CE flashlight. It is about $60 which is kind of out of your price range but well worth it in my opinion. The flashlights that people have linked to earlier from dealextreme are probably very good as well and within your price range. I wouldn't get one though that does NOT requires CR123A lithium ion batteries. Get the flashlights that use 2 x AA batteries.
