– Louis Rukeyser, 2003

"I subscribe to 11 analyst/market letters mainly to try to get some kind of consensus and never seem to. However, if I only could afford to take one it would be yours."

"I bought Apple in Feb '07 on Rob's recommendation and it has doubled in less than a year. My only regret is not subscribing earlier."
