Download Joomla Templates

I want to edit a Joomla template to my needs and specs. I have tried using Macromedia Dreamweaver 8 however i end up with messed up results.

What is more reliable and will not deface my expensive template. I want edit as much as possible of the template.

You may also suggest links of sites where I may download ideal programs (Free or Demo or whatever)

Thanks in advance

You have to have some knowledge of the Joomla! template system and php, because the templates are not just html and css they contain php and some of Joomla!’s template formating system short hand codes
