I never had a 401k but I had a 403b (gov't) which I converted to a self-directed IRA after I retired. Now, I've reached that magical age where I have to take minimum distributions.
Tip: don't tax defer your IRAs. I make 8x the amount that I made when I started making tax deferred deposits to my 403b. Uncle Sam will love me until my IRA peters out which I'll probably never empty.
