For £700, I'd want at least Sora gearing, if you hunt, you might be able to find Tiagra
The real issue is we are all different shapes and sizes and what is right for one can be horrible for another. I don't like black bikes so would never choose one, but it may be that the black bike is best for you

What do your local shops have for sale? That's the best place to start...you have a selection of bikes from probably 5 of the biggest manufacturers in the world, a local shop must have some of them!
