I vote for the 2xAA McGizmo with the Nichia 119 drop-in.
You get 3 modes, the high is 100+ lumens and goes for 2 hours (on Eneloops), the middle is 30 lumens and gives you a very nice useable 8 hours, and the low I don't know exactly but will match something like the old MiniMag 2xAA but go on for multiples of hours of the MiniMag runtime.
As to the quality of the light (tint, warmth, etc) there is no better than the Nichia 119, it is better even than the Nichia 219 and all those CREE warm lights.
And -- wait -- you get the Malkoff VME head (in titanium, of course), put in a M31W, and you get a nice warm color at 200+ lumens for 1 hour runtime.
It also deserves mention that by going the AA route, you can access the most widely available and cheap type of battery, easy to find and especially when traveling. (you can also use lithium AA's for the lightness, weather versatility, and even longer runtimes).
So basically you are set for almost all of your needs, except perhaps very long throw, which you would need a specialized light for anyway.
One thing I disagree with is those posters who like a huge light with a very "low" low mode. Who would carry around a multi-pound large reflector monster to get a handful of lumens out of?? Just carry a tiny light (1xAAA or even smaller) for the very low level output, which you can get with very long runtimes even in that formfactor, and the rest of your light needs cover accordingly!
