Training prep providers in London

Anyone from London here? I am trying to decide which training prep provider to go with for my L1 Dec 08 exam. 1. BPP financial services vs 2. 7city vs 3. Kaplan Financial I would like to know is anyone already signed up with any three of these? If so, what choices did you have to make and what were the governing factors that made you choose? And, are you happy with your decision/any regrets after joining? or positive feedback on these providers??
