Take the money and run?

So... yet again another potentially life-changing question, after someone has unexpectedly graciously offered me another job. Do I go for:

Nottingham - six-month lucrative contract, possibility of permanent. The money involved is obscene, and would be enough for me to do a Masters', but the work itself sounds relatively dull, and it's a continuation of the dual-city thing which has run me a tad ragged lately.

London - eleven-month contract at my old haunt but at a higher grade, with the possibility of extension for another year and who knows after that? The money offered is nearly equivalent, although that'd be over eleven months as opposed to six months with the Nottingham job, so I doubt I'd build up enough savings to do a said Masters. But then London offers stability, a chance to sit still for eleven months and try to build a life. Oh, and listen to Virgin Radio in glorious FM, now I've become a late-night addict to The Geoff Show.

Just to throw another spanner into the works, I've got two more job interviews tomorrow - one with possibly the best TV channel in the world...
