I'm a customer of Joomla Praise and have enjoyed their templates and their extensions. I am a big fan of their replacement adminstrative templates that add a lot of nice features when doing site admin. I simply get more done quicker.
Recently they released their AP-Lite (Administrative Praise Lite) template for free. This is a fast loading, "lite" template that I have found very good as well. Because I'm on a relatively slow connection here in Africa, the extra speed is apreciated. Download it and add it to your template collection. You may find it quite useful.
