Motley Fool

Motley Fool (U.S. or U.K.) is an excellent site for financial advice "for the rest of us".

For example, my bank, in a typical meeting with an "advisor" (read "salesman") had convinced to buy an ISA (tax free savings account in the UK). The setup fee was £500 (a thousand dollars). On Motley Fool I found out I could get the same product with zero setup fee! Luckily it was within the two-week grace period, and I cancelled.
And it is a moments work to go to Fool to look up the best interest rates currently available. And so on.
