I was interested in this item also. So I both PM'd Will and then started to track the thing down. I will go with Will on his order, but this is the email I received this morning which should help others who are interested.

My only problem with the above is that it is nearly 10 pounds to send the thing which looks to not weigh much at all. the 10 pounds would be more like $18. Seems that is awfully high for such a small and seemingly lightweight thing. I guess it depends on how much you want it.
