Not necessarily at all.
Do you believe you could achieve a better return than you're currently getting from your managed fund? This is what you should be focusing on.
I believe ESuperfund has very low fees:
That's less than you are currently paying for a managed fund and you would be able to take charge of your own outcomes rather than paying some anonymous fund manager his take even if he loses money on your behalf.
I haven't personally used Esuperfund but have known many people who are very happy with them.
At that price, and presuming you have reasonable confidence in your own capacity to make money, I don't see why you wouldn't have your own fund, even with a low amount of capital at the start.
The oft quoted 'advice' that one must have more than $200,000 to feasibly start up a SMSF is, I suspect, peddled by the financial advisers attached to the public super funds. They simply do not want to see their customer base reduced by people opting instead for SMSF's.
So, a bit like politicians, they waffle on and on in the marketplace about the need for a given amount to 'make it worthwhile' whereas imo I don't believe such a claim is valid if you actually consider the options.
Think for yourself and choose the logical option.
