looking 4 code sample for php class – custom post type and multiple meta boxes

Im just starting with WP and PHP. I am trying to create a class for the 2 custom post types I need, their taxonomies, and 2 metaboxes associated with 1 of the custom post types. I have the post types and taxonomies well underway but I am having a bit of a problem with how I code the 2 metaboxes associated with the 1 new custom post type as methods of the class. If you know of a tutorial (oop) related to adding metaboxes to custom post types can you pass it along? I’ve searched for a while and come up empty. I’d prefer to use metaboxes than custom fields.

I’m coming over from the asp.net world so things are familiar yet wildly different. Know what I mean?
