Just got a new Maglite - the XL200, and it's pretty darn nifty! Lots of different setting, which I won't really use for the most part, but the coolest thing about it is the way that you can dim the flashlight just by holding onto the button and turning your hand!
The rest of my crew are big fans of surefires, but I don't really want to spend that much when I can get a flashlight of similar quality for much cheaper. I'm also not a fan of not being able to use regular batteries.
