jQuery Dialog Pop Up That I Like and is Easy To Implement

While the jQuery library for dialog boxes is really great and all, it doesn't look all that good straight out of the box. For the most of things, when you're looking for a jQuery pop up/modal dialog box you'd want it to be sleek looking, super easy to implement, customizable and full of features such as an easy way to load content into it via ajax. bPopup does just about all that for me.
