I called a number of hobby stores today and was told by nearly everybody that they had none in stock and that they were discontinued and were not able to order them.
Luckily I found one place that had one sitting on the shelf and I snatched it up real quick! It is the small head version so won't be any good with the Byron setup, but beggars can't be choosers!
