Can any one recommend a good investment letter?

I would like to know if investment letters are a waste of money?

If you want to make money and you have a flexible investment portfolio, The Dines Letter is the best in my opinion. His recommendations have increased my porfolio 300% in the past year. The Dines Letter has been around for a long time and is very successful.
If you are going to subscribe to any investment letter, it is my opinion to use their knowledge to pick the winners that suit your style and profile of investment.
I would never blindly follow any investment advisor.

Your investment letter should be from Nigeria and start out, "Hello. My name is, Moujaad Salaam, the second son of the fourth vizier to the former prince of Congo . . ." Tell them you have a considerable fortune and nee help brining this money to America.

But presently the editor is taking a little time off and only sending out a newsletter once a week. Normally he puts out three newsletter per week with daily posts. I have been a subscriber for probably seven or eight years and he has served me well.
