Finding the best UI

Are there any lights available from other vendors that have a UI similar to Surefire's tactical tailcap? I currently own a Surefire G2X Tactical, Surefire G3D and a Quark Mini 123. Fine lights all, but the G2XT is too bright for many uses and the other lights require too much work to get to the desired setting.

It looks to me light the Surefire AZ2S's tactical tailcap is the best compromise: multiple light levels, both available in a single motion (by the description; I've never used one). So, where else can I find something like that?

Zebralights. 3 lighting levels any of which are available virtually instantly. From one switch! :devil:

If you're after a 'Tactical' flashlight to be used with firearms etc, then the AZ2 or AZ2S would be a good option for you... If you're looking for a two stage pushbutton flashlight with the same UI as the AZ2 then the L2X might be a good option.
