Suggest joomla html editor extension/software

I've started using Joomla 1.5 recently and am using the TinyMCE online WYSIWYG editor that comes with the package to edit articles. I tend to write direct html and javascript rather than use the WYSIWYG functions, I find that after the first time the changes are applied(page updated) most of your html becomes 4-5 separate big paragraphs. Its very hard to find stuff in there cause the content has no formatting -- eg:

<p><span id="psy_ass_span" class="pink_heading">Psychometric Assessment</span></p>
<div id="psy_ass_div" class="pink_box"><img class="img_right"     
src="templates/teamwork.jpg" border="0" />
<p><strong>Emporkommen</strong> uses <strong>Psychometric assessment</strong> as a tool     
in order to gain insight into a person’s personality and psychological thinking. It can 
help develop team spirit in t
<script src="plug开发者_运维技巧ins/editors/tinymce/jscripts/tiny_mce/themes/advanced/langs/en.js"   
type="text/javascript"></script>
he workplace and assess an individual’s priorities.</p>

Plus obviously there is no code highlighting in the editor so you can't figure out what is what. My question is, do you guys know of good(preferably non-commercial) extensions or other softwares or techniques that can make editing html code in Joomla 1.5 articles easier even after applying changes several times.

You should try JCE - http://www.joomlacontenteditor.net. It's a WYSIWYG Editor, but it has a great Code Editor with syntax highlighting and stuff.
