Went to my local Currys PCW superstore, which has a phones 4 u. Wife needed an upgrade, and found this little beauty going for £129 when bought with top up. Make sure to ask for the band d, which is unlocked to all networks, as she has a Virgin sim, but assistant advised for that version. If paying by cash, you'll need to buy £20 worth of top up.
For this price, it's a blooming bargin! :D
