I used Investools a long time ago in 2002, and paid the $3000 for the seminar. Be aware that it's for intermediate term traders - not day traders. I also found the same analysis for $10 a month at another website wallstreetcity.com (now dead). Investools did not work for me. I bought their "strong stocks" on the green arrows, and the stocks sank further. But, this was the bear market.
For an alternative fundamental analysis, try investors.com - the William O'Neill Investors Business Daily website. Also with only a basic BusinessWeek magazine subscription, under $50 a year, you can do great stock research on the BW website. But no screening tools are included.
For good screening, try Reuters Power Screener - free level. MSN also has basic screening tools.
