Do you think the ZAR/USD exchange rate will improve in the near future?

I have been wanting to buy some electronic equipment from the USA but I am not ready just yet to buy it. It is not available in SA.

I have been looking at the exchange rate over the last two months and it went from a low of R15.71 on 28 January to R17.15 today. I also checked the pricing on the website and while the product pricing remains the same at $539, the shipping pricing has now gone up from $102 to $105.

Do you think it's a good idea to buy it now or do you think the exchange rate will improve soon so that it will be cheaper to buy it in a few months when I am more ready to start using it?
