I use 2 hard drives and ghost an image of my main drive to the second HDD that way if it crashes on the main drive you can reinstate back to the original configuration. To your question you might try
ASTALAVISTA.BOX.SK and do a search you may still have to pay a price but it would be very very cheap. However a warning, some parts of this site are a bit dodgy so you should scan your system after downloading anything from there.
