GeorgeStorm - The Trek 1.2 would be spot on really, in terms of a good quality well specced entry level road bike it's really good. I wouldn't bother with road bikes sub £500 to be honest, far too much compromise in quality or ride like crap and weigh a ton. As the saying goes: Strong, Light, Cheap.... Pick two of them!. I would either find an older model or save the extra few quid for a 1.2 (or just buy a hybrid for now). Size wise a 56cm should be spot on, the most important size on a road bike is the top tube length which will effect the reach to the bars, you can tweak it a bit by running a different length stem +/- 10mm without effecting the handling too much.
