Like the other poster said, check out what others have said about ESuper. I have just started my SMSF and was considering them, as I had the impression that they were cheap, but when I read the fine-print on their website, I changed my mind. Yes, they seem cheap but you have to use their nominated bank, and I think you are charged extra if you trade over their limited number of shares, there were additional costs and restrictions. I researched, and came across Green Frog Super. Still cheap, a great easy-to-read website which clearly and simply outlines their charges (I didn't have to go searching the fine-print like I had to with ESuper), and no stupid restrictions. I can use my own bank, my preferred online broking account, no restrictions in trading, eg, I can purchase shares outside of ASX300, no limit or extra charge on number of trades, very responsive to my emails and calls and queries. So far so good, am very happy.
