Where to buy a chain breaker + sprockets/chain

Did anybody buy a chain breaker recently? I would like to do the next sprockets and chain replacement on the 800 myself. I see some on Takealot but it seems to be for bicycles mostly... As long as it can do the job, does not have to be high end and will most likely be used 5 times max.

Also, where to buy a good quality chain and sprockets? Mine still has the 8mm bolts on the rear sprocket. New ones are 10mm. Preferably in the Northern Suburbs or even online somewhere...
