Um... let me put it this way. The light *is* the extras. 4 modes, intuitive UI (even for the technologically challenged), unbelievably durable, crazy bright, just about perfect beam, excellent warranty/CS, excellent battery life, etc.
You pay $160 up front, but you save money not buying a whole bunch of "lesser" lights, have them break, and get a Clicky anyway. Just trust me on this one.

The Clicky, IMHO, is the best pocket EDC light out there. I've had my 140E for a year now, and it's still every bit as amazing as when I first got it.
However, the Surefire G2X Pro is pretty cool too. I would get one now before the price doubles, as it will in a few weeks or so. Not EDC material, IMO (too big/heavy), but a very nice light nonetheless.
