Does anyone have any frameworks to setup custom post types and related actions/filters?

So I know that setting up custom post types ranges from just registering them to adding custom permalinks, custom sorting, customizing columns in the admin, etc. I was wondering if anyone had a template or framework that they use regularly to set up custom post types in projects? Do you start from scratch every time or do you have a base line you start from that you customize?

The Custom Post Type Demos by toscho hold some nice basic classes, that you can use. I’d recommend taking a look at this source (as he’s a trusted author and a pretty good coder).
