Make a budget. The box sets are fine for beginners but you will soon grow out of it and will need better clubs. If you aren't the type of guy to take something up and then drop it then I would rather recommend buying 2nd hand stuff from the pro shop. Unless you are looking to play 3 or 4 times a year and not really take it seriously. Nothing has changed much in terms of tech in the last couple of years but there is a big difference in quality between box sets and proper off the rack equipment.
I would look at a year or 2 old set of irons. A 2nd hand Adams set from 4-PW won't set you back more than R1200 and I have seen a couple of drivers like TM R9's or Cleveland Launchers which are only a generation old going for R1000. In terms of a putter you can get the Cleveland classic online for R499, down from R699 and it is one of the best quality putters for your rand. If you need a gap wedge then the TM Rac Satins are R650, and still some of the best wedges around.
So to sum up. 2nd hand driver +- R1000 (go for a higher loft here, 10 degrees + if possible) 2nd hand irons R1300 (ask for GI irons, a set where the 4 is a hybrid, possibly the 5 too) You might need a 50-52 degree wedge so thats R650 and a putter for R700 (though look second hand there too, there are occasionally very good deals) So in total R3650 gets you a lot more than the R2000 box set and you won't need to replace your equipment in a couple of months.
Oh and any left over or spare cash you have invest in a lesson. Once you have the basic fundamentals down golf becomes a much easier game, and the only way to get those basics correct is by lessons.
