PICkit 2 programmer is open source, so you can build your own:

PICkit 2 was originally built by Microchip as open design programmer with the schematic, source code and firmware available to boost the popularity of the PIC devices. Because of that it is easy to build a clone version of the original device. Most of the clones will produce unregulated 5 volt VPP where the original Microchip PICkit 2 provides adjustable VPP output to allow 3.3 and 2.5 volt parts programming. The schematic I have used is based on the original PICkit 2 without programmer-to-go functionality. That functionality allowing a hex file to be downloaded to the PICkit 2 to later program PIC microcontrollers without a PC with a simple pressing programmer’s push button. I do not think that functionality is required for a hobbyist but allows simplify the schematic by omitting two 24C512 EEPROM chips. The Eagle Files designed using only thru-hole mounting parts.
