Does anyone know if there is a good chart somewhere showing where the lowest fees are for investing?

I know that index funds have low fees, but I'm also looking for which mutual funds have the lowest fees. 

It really is amazing how high the fees can be at some places.  We try to get a high percentage in return for our investments and then some of that return is eaten up by investment fees.

My goal is to look into all of my investments to make sure I know exactly what tyoe of fees I am paying.  If I find something with a high fee, I will shop for lower investment fees.
