Recommended short-term PAYG provider?

Hi!

I'm currently on Orange (and very happy) but want to take advantage of some of the great offers on Orange out there at the moment such as:

Obviously I need to transfer away from Orange and back again if I want to keep my current number, so I plan to go on PAYG briefly.

Who is best in this case? Virgin, easyMobile, Fresh? Do they have a minimum amount of time you have to be connected before they'll give you a PAC code?

Many thanks in advance,

Think Virgin is usually the recommended option - turnaround of just over a week.
