What is the Best Chemistry Editing Software for Taking Notes and Studying?

[p75213]

Hello,
I am teaching myself chemistry using the khanacademy videos. I am using a wordprocessor to take notes and would like to supplement it with a suitable chemistry editor. Could somebody recommend a free or inexpensive editor?

Try ACDLabs ChemSketch.
