So many have been made and I've only had or tried a handful so I'd like to hear other opinions. Here are my top 3 not in any order:
M30-versatility of using any single battery and the optics make it a pretty good thrower. Currently a favorite travel light in a vme head and an aa mdc body running a 14500(capacity now rivals 18350s which isn't great but works for me) with the option of using a single aa if needed.
M61w LLLL - favorite camp light and chore light. Really nice beam and tint doesn't freak you out for close work. Currently in a surefire g2 with a malkoff tail cap so it can tail stand for a night light, and use silicone toe shields to convert it into a useful lantern.
M91b N v.1 - ok, maybe this is my favorite. Really nice tint and beam and versatility. Currently in md2 with hi/lo running either 18350s or single 18650. Have oveready extender to run two 18650s but really haven't used this set up much.
