Reconditioned phones, but as new, and with 6 month warranty.
Just bought a motorola V220 for £35
Listed as £45 here, but if you already have a virgin sim card, and buy through your online account, you get it £10 cheaper because they don`t need to supply a sim/joining pack. (use together with free sim pacs from a few weeks ago)
I think the 10 discount applies to all recon phones.
