I agree - the lumintop SD Mini, to me, was about perfect size, finish, etc. Not sure how it compares to the SC64 family (you meant SC64?) - probable the SD Mini is a little bigger all around but has an SMO reflector and bigger head for better throw.
Look'n at the specs, the EDC05 is a closer fit but smaller. So the SC64 is about in the middle of the 2 at 92.5 mm long, 24.5 mm head diam.
Yep that's pretty darn close to cloning a Zebralight. Not much recent info - says $38, $45 shipped but I wouldn't trust ordering from ylplight.com, hhmmmm. Who knows if it's real yet.
