That last batch (March 25) was completely backordered, so none of the standalone controllers were left over for sale on the website. However, there is another batch (large!) coming in on April 25. So, I am re-enabling the backorder PayPal button for the controllers. If the whole batch gets backordered before it arrives agian, then I will have to disable the button again - but I doubt this will happen, as the next batch is four times as large. So, get your backorders in! When the controllers arrive, I will be shipping them in order of who placed their orders first.
