Well to start off with if you look at the offer of R310987 to the pound a month I think you looking at about 28k a month and the station allowance is not much to right home about for Bloem and East London it is about R1600. At least you get a good medical insurance not to bad pension fund. The JHB allowance is much higher than the other one's. I think it is about R7500 not sure. TFC wise you can have a look at ACSA website where they list the average movements for these station. Bloem being the least then EL then JHB being the busy one of all station in SA. Housing in the other two towns are high but not crazy like JHB and the towns are also nice and relaxed not a rush pit like JHB. Good climate all around.
Hope this helps feel free to ask more,will se where I can help.
