Perhaps not ideal for yourself Marc, but for others, I've just purchased a Xiaomi Mi1S from China for circa $300.

Android, dual core, blah blah. Basically similar to Samsung Galaxy S3 but not 4g compatible. Screen is somewhere between iPhone 5 and Galaxy sizing. Comes pre-loaded with MIUI.

Fantastic value for money and being android, easy to hack for say an Aussie version of MIUI (which I have done). I've also got an iPhone5 and must say that I'm neither here nor there on which is better...but the Xiaomi was 1/3 the price.

Even better still is the Xiaomi Mi2, but it is extremely difficult to get your hands on. Worth looking into, particularly if your having to buy outright or replacing a lost/broken phone.
