Welcome
I started off with Share Saver as well, but it is very limited and I wouldn't recommend it unless you agree with their investment philosophy - top 40 + midcap
Your choice between platforms (especially if you are just starting out) is more or less limited to EasyEquities and ABSA's ETF Only account...and they are very good platforms.
* EasyEquites - very cheap, very easy to use, access to all shares, ETFs and ETNs on the JSE. Has baskets and bundles available for extra guidance. Also has value orders which makes it even easier to use.
* ABSA ETF Only - also very cheap, more advanced features (stop loss, limit orders), access only to ETFs
Both support TFSA accounts. Of the two I favour ABSA but nothing stops you from using both which isn't a bad idea at all. You can do your serious investment portfolio on ABSA and speculate with shares on EE.
