BTW to anyone else following this thread. Still open to other ideas as to what you would do with R10,000 a month.
I'd find out if there's a tax advantaged account where you are similar to an RA. If you're paying 30% tax, putting the money into something like a RA or 401k etc would give you those returns straight away. If you're in the states or UK you should be able to go with a Vanguard fund, which has some of the lowest fees around. I wish they'd open up an office locally, but I don't think there's much chance of that.
If you don't have access to any of those and do want the money in SA then I'd do a split between DIVTRX and STXIND personally. One of the reasons I still like the indi is that it's a great rand hedge:

I already own a chunk of both, more indi than DIVTRX, so currently I buy the DIVTRX every month just after payday.
