Don't go satellite unless it's your only option. It is very expensive and the OOB rates are pure extortion. We talking hundreds of Rands per GB.
I have no option. I live on a farm. We have no copper and we are too far from the exchange (4Mbps max speed available in town). There is no 3G service only congested EDGE. There are no LOS wireless or microwave. For a 2Mbps/10GB I have the privilege of paying R750/pm. Fortunately the provider supplied dish and modem FOC. You can expect to pay R10K+ outright or R400/pm, and the R2k installation fee.
