I am most definately going to buy the enduro i reckon.  Cannot wait!

I considered HID but i dont want to prat around with cables etc, this badger is plug n play!

 How did the previous models work? Reliable? bright enough? value for money?

Bright yes, depth of beam lacking, realiable, not so much

Only from what i've read and seen not form personal use. 

I've had the older Race Turbo for about 18 months now and I've been really happy with it. Its certainly bright enough, on High (the middle setting) its about as bright as Hope LEDs on their brightest. I saw the new models at SITS and saw the joystick in action which looked really bright even though its tiny so the enduro should be bright enough to set fire to the trail infront of you.

Reliability wise the only thing thats gone wrong is that being a numpty I stripped the thread in the mount but USE replaced it for free within a week. The new model has a different mount now anyway.
