> I just got a "refurbished" xperia Z5 compact for £230 from GiffGaff. Their refurnished phones are basically phones that have been returned within the 14 days, then checked over and resold. Really happy with it. Managed a 7 hour hill walk the other day with GPS tracking my route and only used 35% battery. Normally get 2 days between charges.
I'm also an xperia convert (mine might actually be a Z3, can't remember if 3 or 5). Got this one from a mate for £70 second hand when he upgraded. The updated models have a few extra bits, but impressions from this one are that's it's tough, v good battery, and I've had zero problems/crashes/anything with it in several months. Takes a big SD card too.
