Like I said, it was a ridiculous purchase, although I don't recall paying $54. But then I tend to suppress detail like that. ;-)
If you were to order now, you would get a complete, updated fan.
With the JB palette, which was a fabric per fan, I recall(?) buying updates for it (it's just a screw holding it all together).
With the Balis, you can see on that link in my previous post that the updates are available for a nominal fee - nominal once you get over the cost of the initial fan.
New fabrics are added to the collection at least a couple times a year (probably tied to Quilt Market)- I don't know how often they plan to issue updates. I guess when there are enough fabrics to warrant production of the fans.
