Buying a PICkit3, genuine or clone, doesn't help you. Because PICkit3 doesn't support PIC16F15214 with Microchip official tools.
You can program PIC16F15214 with PICkit2 and PICkit3 using either PICkitminus or PICkitplus. But if you want to debug or use official Microchip tools, you need PICkit4 or ICD4.
