the XML Based units are the best so far. you really can't beat the insane throw and brightness for $28 shipped (amazon ebay anywhere pretty much now) the new one has 3 modes with a lower "low" which is what I used most of the time and its more than enough usually when its really dark I throw it on hi "just because" why not.
WOW niuoka found it for $23 gonna order two of them at that price and get free shipping (christmas gifts)
