The expedit is actually discontinued, but the kallax which replaces it is very similar. The door and drawer units for the expedit/kallax systems are pricey and not worth it in my opinion. I think they function best as open cubbies or with bins sized to fit exactly.
The Billy shelves come with different styles of doors -- solid or glass or a combo. I find the Billy units too shallow for my system of fabric storage, but they are perfect for books, binders, magazines.
There are several free standing wardrobe systems that might be better choices for your fabric needs, depending on how much space you have. Don't overlook using kitchen cabinet units either -- I've found some in the as-is section for as low as $5 a cabinet-- and they make a great base for a sewing or cutting table. They also house the various wonderful Ikea organizers perfectly.
I have a lot of Ikea furniture throughout my house and it stands up to a lot of use, is a great value for the price, and is pretty flexible for re-purposing in other areas of the house later if you want to change it up.
Another thing to think about would be to look for resale on Craig's list or your local classifieds -- I've found expedit units for less than half of retail in very good shape.
