Winter training lights?

After lots of reading or reviews and forum discussions, I still can't decide what light to buy for winter training. Needs to be bright enough to cycle on unlit country roads, needs to be cheap(ish) less than £100 at the very most, preferably £80. Any advice would be much appreciated.

Burn time on mine is approx 40mins on brightest beam, then it drops to a flashing mode. Not a problem since my commute is about 30 mins. Lights the road up well, even on the unlit roads i cycle on, and i've even had cars dipping their lights coming towards me.
Theres also a Power Drive model for about £80. And you can buy replacable rechargable batteries for them.
