Thank you all for your great replies, you have given me a lot to think about.
I went to JE James Cycles in Rotherham yesterday and had a good look round, they had lots of lovely bikes and I was pleased how many they had in my price range. One thing i did find surprising was the chunkyness of the frames, I've never really studied road bikes , and in my mind I thought they would have super skinny frames, but some looked as chunky as mountain bikes. Not a bad thing, i thought they looked really nice, as i like the chunky mountain bike look, so at least they don't look as alien to me as i thought they would, but the tyres are so so thin, I know why they are like that, but coming from MTB's they look perilous
Looking around it seems if i go for last years model i can get a carbon framed bike (but lower spec components),I'm not sure what the pros and cons are regarding carbon and aluminium, i have got a lot of research to do, but i like researching purchases, I will be checking out all your recommendations and taking your advice seriously, thanks again.
