Dear Dev,
I have experimented with 16F628 and home brewed pic programmers. I will go with OM S Chandra Sekhar. It is easy to homebrew a serial port programmer.
I have attached a rar file herewith – content this is my entire “PIC programmer folder”. I have homebrewed this one successfully and is working with 628, 876, F84 and many other PICs.
Modern PC’s have dispensed with Serial Port as well as Parallel port. In my experience, the USB to Serial port don’t work well at all in many cases. However, you can find “hidden” serial port in many modern PC mother boards. It is usually called “serial port header”. You can connect a “serial port header to 9 pin or 25 pin converter” cable and still do all the good things. I have attached a pic of one such adapter. You can home brew this one also!

One solution would be to use a usb - to - serial converter and then
wire up a serial port based PIC programmer.
If you want the direct USB programmer it might be simpler to buy from Microchip.
