For $15 US you can replace it (or have a back-up) with the new Snap from Microchip. It has pretty much all the functionality of other Programmers, except you cannot power the device from it. Microchip seems to have finally worked the bugs out of the PicKit4. I have one I use regularly and it works as advertised. In fact, I have an old PICKit2 clone, PICKit 3, PICKit4, IDC4, Snap, and ME Labs U2 Programmer. I haven't touched the ancient PICKit2 in years. If I have issues where I suspect the Programmer, I can grab a different one to verify. The Snap makes for an inexpensive back-up.
