People also seem to forget that using computers that are publicly accessible at libraries to get the rars a few at a time is a feasible option, even if your home internet is slow.
If you use a flash drive just for the purpose of transporting files from the library to your home storage, an 8 gig drive would suffice to get 10 rars per trip.
Most libraries at least have broadband, so even if you only have dial-up at your home, these projects can still be within reach for you.
