Supermarket South African wines

Before my talk in a fortnight, I'm trying to get an idea of the range of South African wines that are available in local supermarkets.
There are a number of bulk producers I see, like Kumala (Constellation) and Arniston Bay. But of individual vineyard producers, I only regularly see Nederburg and at the moment Boekenhoutskloof.

Spier seem to be getting a few different wines into Tesco and Morrisons. Ken Forrester is in a few.
if you see any interesting SA wines locally, please let me know!

ps - all the wines for the talk are here and waiting!
