Does anyone have a MK3- USB (VE.Bus to USB) for sale (or rent) in the Johannesburg/Midrand area. 

Or where I can get one between now and Friday in Durban?

Have you tried just ordering one on eorder.victronenergy.com? They have a warehouse in Edenvale and can deliver to your door within a day or two. Of course it's charged in Euro, and shipping cost is going to be half of the order, but if you are desperate that might be a way?

Did you already check with suppliers such as SonopSolar or Current Automation? Small items like these should almost always be in stock, Victron usually holds heaps of stock.

Isn't there a crowd called Tytech in Durbs?

Sorted, got one from Current Automation in Jhb who will deliver by Friday.
