Excellent Free/Inexpensive Financial Sof

I am looking for freeware/shareware/inexpensive software or web sites that will help me with technical analysis or stocks and especially mutual funds. I am looking for something with buy and sell signals, etc. I'm wanting something very professional, very in depth, a solid product that is either free, or reasonable in cost. I'm willing to take suggestions of products/sites that cost a little more as well.

part 2 of question
What is your opinion of the various software products/web sites - services available today - which ones do you suggest to others.

I'm really hoping to generate some discussion, and I appreciate your feedback.
