If you can afford a computer, a DVD burner, DVD media and internet connection you can afford to pay for the software that you use to run that hardware.
Put it in perspective and you will see that, at least where i live, the price for
CloneDVD equals aprox 15 DVD-Rs.
If you can't afford that perhaps you should be spending your money more wisely then on computer peripherials.
