In reply to nickinscottishmountains:
The Volant series has a really poorly designed frame to be honest, its super harsh and unforgiving which, on an entry level bike isn't usually the desired feel. Go to a few bike shops and test ride as many in your price range as possible. Then think about what you're prepared to compromise on having ridden a few.
As a rule of thumb, Alu bikes start to get good at the £800 mark when you start to see Tiagra as a minimum groupset. I'd look at £1000 and get 105 with a nice comfy frame like the Cannondale Synapse 105 (admitedly its just over the grand but its a lovely smooth ride with great componentry).
