Well said. For index funds it should be almost infinitesimal with how much work that actually takes. Typically international will run you more but that also makes sense. Bottom line is do your homework. I am also a proponent of combining 401k and Roth. Gives you more control over your taxes come retirement time.
One of the first mistakes I made as an investor was to open a "managed account" with a quarterly advisory fee. After 3 quarters I ditched the advisor and learned to manage it myself.
