We have a tutorial for creating product options in the works. It will start with Creating the Product insert pages for the Administration section using data assist, then go into adding the option drop down lists in eCart.
They will not be video tutorials, but they should cover the information in depth. We will be using the new eCommerce database:

A description of creating the product insert pages can be found in the last post of this thread:
