I can't believe no one has mentioned the EXCELLENT Opalec Newbeam Mini Mag conversion yet.
According to the flashlight pros at CandlePowerForums, this flashlight has the most rock solid regulation of any flashlight. If you don't know WTF that means, it means basically it will put out an extremely steady amount of light - it won't grow yellow and dim almost immediately like the old 2 D cell flashlights we had when I was a kid.
In fact, Opalec had to add a tiny red led to go on as a warning when your batteries are almost dead because you can't tell at all from the amount of light emitted from the flashlight.
I'll tell you this - my sister ain't no gadget nerd, but she snagged my first Opalec Newbeam the first time I showed it to her!
Since its a conversion of a Minimag, physically it is a minimag. Except it has 3 (4 if include the red LED) LEDS and is regulated.
Converting it takes like 3 minutes. Let me tell you, I have put AA batteries that were essentially dead in them, and because it has a step-up converter, the light still shines bright on these "dead batteries" for hours!
At about $21, it costs a lot more than the original Maglite, but compare that price to a regulated Surefire!
You can get them at Brightguy or BerkeleyPoint.
