Cheap phones really are capable these days. I just got a 2nd hand Lumia 520 for ZAR1000 (about $100) and it can do everything my much more expensive iPhone 5 can. It's good enough to be my primary phone which is pretty amazing. Even has wifi internet tethering. Windows Phone 8.1 is a solid OS. The Lumia 630 with dual sim looks very appealing to me as soon as it's available.
