Are you self-sponsored? If so I wouldn't advocate such huge expenditure when the contract categorically states that they reserve the right to change prices at any time during your training. Despite emails assuring me that they have never done it before, I just couldn't justify the gamble with such huge sums being put into it.
In short, if you're looking at sponsorship I'd say go for it, if self-sponsored I'd probably steer clear. However, everyone has their own circumstances, and of the integrated schools, I would agree with you it seems the best.
If you want to know anymore about the selection process etc. please feel free to PM me.
