In reply to jonathan watt:
For that money, do what I did on the same budget - get measured properly, find a frame that fits your body and style and build what you want around that.
If you get what you want/need in sales and build it yourself, you'll have a very nice bike at a very good price.
If you do go "off the peg", note it will have rubbish wheels and tyres, so budget to upgrade them right away, especially if you want a good climbing bike.
