For weapon mounted Tac-Light I found Streamlight TLR 1's or 2's are the best. But the price range on both are way over the $50 budget you have. But Ebay does have some cheaper Chinese made lights that are airsoft weapon grade for that price. Meaning they may or may not hold their function when you run them through real weapon application (recoil, holstering/ unholstering, banging on walls..etc) But those are also aluminum and sometimes they do work...but I would not trust my life into one of those. For Holster I'm +1 witht the Don Hume.
