Might be the first of many but CycleSurgery are doing the What Mountain Bike bike of the year 2010 at £1799 instead of £2000. This is the cheapest around for this by a long shot.
All Trek are only available instore but worth a chat with your LBS as many of the bigger ones (Evans/Rutland/J E James etc) will price match.
Some blurb here:
Trail Performance, Patented
Like nothing else on the trail. It's our do everything, full-suspension trail bike that's equal parts efficient climber and commanding descender. The Fuel EX 8 comes equipped with proprietary DRCV shock technology, for a bike that feels just as capable as longer travel bikes.http://www.trekbikes.com/uk/en/bikes/mountain_full_suspension/fuel_ex/fuelex8e/
