Lister, there will be a huge surplus of 2009 bikes on the market in 3 months time when all the 2010 bikes are out so if you can hang on do so. But looking at Sram and Shimano's price rises, next years bikes will be more expensive with less quality fitted to them.
If you are going down the C2W scheme, make sure your company is not tied to one retail outlet so you get a better choice. If you want a descent 4" xc bike then a Giant Anthem X2 for £1600 is my choice (Some places are doing it for £1400). Great review, good spec and a top ride. You will save 40% off list so comes in at £960.
