R570 something for 50/25Mbps Openserve. Used to be faster but they raised their prices. Not sure it's possible to downgrade further when they increase them next time.
Currently paying R1000/pm for 100/100 line, but I'm getting 1000/200. The network provider replaced the ONT last week and my speeds have been consistently sitting at 1000/200 since then. Will probably get "fixed" soon.
Around R520 for a 25/25MB line. Afrihost/Vuma. Works fine for work, studies, internet and streaming. A bit slow for downloading bigger games from steam etc.
