Training

Looks like I be off on training down in London, Wed/Thur/Fri.
Got a nice ish hotel to be staying at, but thought I'd see if anyone in the area would be interested in meeting up?

How far would you go?

Assuming all other things being equal, how much of a pay rise would you need to be offered to consider relocating elsewhere in the country?

And assuming the mythical job fairy were to offer you pretty much the same job, but 100+ miles away, at what point would it be a 'no brainer' for you to accept?

Would the same apply to relocating out of country? (Assuming no hinderances like work permits/language barriers etc.)
