Paul I found the cheapest way to pickup an HSDPA modem is to take the MTN MyChoice TopUp 75 contract. You end up paying about R83 per month and you get a free modem as well as R75 airtime. Then since my ADSL line hasn't been installed in my new house yet and MTN has only EDGE coverage I bought a Vodacom Prepaid Starter Pack (R2) and then charged the airtime up through my online banking to buy a 1GB data bundle (R289) using a mobile phone – no calls. Bigger bundles are available as well. If you run out, you can recharge your bundle when it is under 10MB remaining. Quick and easy.
