Postgraduate education in UK (London)

Dear friends,

I am looking to take a 1-year course (most probably in Marketing) and I would like to ask for your advice as to which school/university to choose.
I have checked FT ratings and am well aware of Oxford, LBS and LSE, but I would like to see if there are schools with more democratic fees and still good education quality, i.e. a golden middle... Look forward to hearing your opinions.

Thanks in advance,
Olga
