Thanks for your feedback....I may have to try the quark as I am reading a lot of good things about them. Don's work is simply amazing, I may look into the saphire 25 or a bargin in the market place.
Ra Twisty intrests me- I am a bit partial to twisties and single mode- but I guess that is why I have become somewhat disinterested.
Oddly enough the light that has recently impressed me the most is a "lowly" 2D Rebel Mag.
Take up diving and then you can start all over with dive lights!
Instead of the latest and greatest why not look around for vintage lights? I recently was gifted a "Bright Star" flashlight which had been hanging around a convent for decades. It has an amazingly bad beam and seems nearly useless but it is way cool in its own way. I need to dig up some history on it and post pics but I haven't had time. It has piqued my interest in obtaining other vintage lights.
