I could actually get the whole set for you, but it would cost $40 or so, plus shipping from me to you. They're actually sold new as a complete set, but people break them up and resell them individually.
The reason I haven't persued a set for sale on SDM before is because I'm not sure there's demand for them at $40-$45 except to serious collectors (especially since they come in a rather plain plastic bag, not a box.) Although if you folks tell me you'd be buyers at that price point I can work on getting them in stock.
