redactor

I myself have been struggling a lot with nice wysiwyg editors a lot. I find most of them not very design friendly, and many pose problems when it comes to pasting text. I find the "redactor" editor very convenient, but it is not a free editor. I have no skills or whatsoever in integrating editors, but I think this editor would really add something to drupal. There are a few questions I have:

• Is there a guide that helps me with integrating a basic editor (by assigning a class to a text area element and adding the js files)
• Is the community willing to use an editor obtained illegally?
