I absolutely love my LX2. I bought mine from batteryjunction. It is hands down the best light that I own.
I REALLY was in love with my E1B for EDC...until I tried to use it at a low-light shooting course that I took. Holy hell, I will never use either a clicky OR a two-stage light ever again, unless the UI is just like the one on the LX2. Often I would light up the target, shoot, attempt to turn off the flashlight and then move, but I had inadvertantly clicked the thing on instead of just momentary on, so after moving, my light was still shining bright when it should have been off.
Then when that didn't happen, I was having trouble with the thing coming on in low mode when I needed high. About halfway through the course I switched out to a G2 LED and an X300. Only problem with the G2, 6P, etc. is that they are just too damn monstrous to carry around in my pocket comfortably, plus they don't have a pocket clip. The LX2 is just skinny enough to make a world of difference for pocket carry. I also love the clip, but I carry bezel down.
None of those problems with the E1B UI are issues with the LX2. It is a twisty and you cannot possibly activate the light only in low-mode by accident. That is what I love the most about it...aside from the fact that it is brighter then hell and has awesome runtime.
I can't wait for the LX1 to come out. I'll be buying on for sure. Until then my EDC is the LX2.
