Greeting to All,

I have recently found the Old School Value Investing Blog which is operated by one Jae Jun. He is a value investor who follows the principles of Graham, Buffett, Greenwald, and Ponzio. As a yearling value investor myself, I find his writings informative and not too esoteric. He also offers a premium stock valuation spreadsheet for a yearly price of $357 about a dollar a day.

Question? Does anyone know anything either first hand or otherwise about Mr. Jun's work and/or spreadsheets? I am seeking input regarding his product both good and bad before considering a purchase of said spreadsheets.

Thank to all in advance for your time and consideration in the above matter. Any and all information will be greatly appreciated.

Respectfully, Mike
