That's if you're in Oxford (£30).
If you go to Michigan, you get $90 per week, because you won't get any meals at w/ends.
Not sure what the Jerez figure is - perhaps one of the bunch going out this month could post...
As far as money goes, don't let it stop you - there's always a way round it... as mentioned several times b4 on Pprune, HSBC does an excellent professional development loan- I used it to consolidate all debts til when I join BA (actually can then pay it back 6 months after starting on the line). I think amounts can go up to 2/3 of your current salary, or about £8000 (willing to be corrected on the latter - my memory's not that good!).
It's important to emphasise the point that if you want it badly, money will not stop you (esp. when it comes to applying for sponsorships - slightly more consideration is required if you go self-sponsored).
