I also have the Maglite with the LED adapter thing. I really like it. I had the light for 10+ years before finding the LED thing, it has given my little Maglite new life...
But... I don't think that would work for you as you are looking for a 1" one. I have heard a lot of good things about the Fenix brand.. My cousin has a couple and they work better then any of mine. But then again his two cost more then my eight or so lights. But, Im sure that's still cheaper then a Surefire.
There is also a guy on here who makes flashlights. Did you check him out?
Here is the thread about him selling them...

If that doesn't work, when I found it he was at the bottom of the first page in the gear for sale area.
