I'm using PHPWebsite right now. I like the layout of the admin area, but I think the support and updates are a bit slow.
I'm looking for a new CMS myself, and I'm not sure which one to go with for a small personal site. Plus, I'm an amature, so it needs to be easy to set up.
I tried php-nuke a while back when I decided to go with PHPWebsite. I kept getting lost in the admin menus, and couldn't make it act exactly like I wanted it to.
I'm interested to hear any other experiences from post-nuke vs. whatever CMS
