OK, the Lumapower M3 has one of its 3 tubes options with the 1xCR123A you want, it also has TWO different clickies coming standard, a 2-stage and a tactical. Has the new CREE XR-E LED. Possible disadvantage for you - you don't want the other tubes (1xAA and 2xAA) and right now the light is sold as a package, so you may pay more than you want.
The SF L1 fits your requirements, but will be available with the new LED emitters in July. If you don't care and don't want to wait for that, the L1 would fit the bill even today (with about 2 different generations to choose from).
the latest McGizmo, the Ti-PD-S, if you are willing to pay the price, does not have a clicky as such, but a "piston." So you need to decide if that works for you.
Others? HDS/Novatac when out could be a possibility (but on the expensive side, again). The P1D CE fits most people's requirements, but is not a clicky of course.
