SEP IRA vs Solo 401k vs Individual Brokerage?

Val: I'm a self-employed blogger making about $90,000 to four taxes. My husband will have a full state pension upon his retirement for which he'll be eligible in as soon as 10 years. Do you have any tips to help me make this decision? Daniel: Can you just describe or kind of simplify what the different options that she's talking about are solo 401k versus a SEP IRA and what those accounts are?
