+1 on the Brinkmann Maxfire LX. It's a great Polymer body which accepts the same Surefire P60 lamps.
I have my last one for sale on ebay. I was going to save this one in addition to the 3 I already use, but I'm moving so I need to get rid of some things. LOOK_HERE_FOR_A_CHEAP_MAXFIRE :thumbsup: Along with a bunch of other lights and stuff.
I don't know if this would be considered a clone, but you might want to check out the Pelican PM6 (both Xenon and LED versions); it has a foward click switch and removable clip.
