    I am looking for a device using which I can record / save variations in current on PC. Current is in few mili amps.

    There is free oscilloscope software that you connect your probes to the sound card. Im sure they can do current!

    You can also buy USB style data loggers. You would need to build an electronic interface to convert the current of interest to a voltage signal. If the current of interest is in the 4-20mA range you can actually buy USB loggers specifically for that range.

    Have you concidered using a shunt restistor with a voltage controlled oscillator for a signal, then simply recording it with either sound card scope software or similar? depending on how accurate you need to be, a wave file might give enough of an indication.
