What are your experiences with 'self directed' 401ks?
I use the self-directed option for the 457b plan at my job, which basically allows me to invest in any mutual fund or ETF. We get Schwab as a broker, so the commissions are reasonable. Personally, I think it's great, because some of the funds offered by the core plan are limited. Generally, the trustees of your plan are going to limit your investment options, as participants generally make poor investment choices (even within the limited options available in a 401k) and may sue the employer after losing their savings. If I was a decision-maker in this area, there is no way I would ever sign off to allowing employees to mess around with options.
