I just checked Tamiya's website, and it lists their GFS "Apple" aka, part number 7255028 : (GFS Receiver Unit: 53447 - MSRP: $89.00 ; Discount Price: $21.50) as 'discontinued' and no longer available. 

Does anyone know where I can get some?  I need 3 apples (I already have the Tamiya base units and LEDs.

Thanks.
