Samson Airline Gibson-style transmitter?

[Esquillama]

Hey, where can a guy find a Samson Airline Gibson-style transmitter(AG1)
for a decent price? The only price I can find them at is around $170!
Now, this is TRANSMITTER ONLY. I was lucky enough to score the
reciever from a former bandmate, but I need a transmitter to complete
the deal. Does anybody know of a place that doesn't want blood
for just the transmitter? I could buy a whole new set up with both
the transmitter AND reciever for about $230 or so. It seems a shame
to pay only $60 bucks less for just the transmitter.

Any help would be greatly appreciated.

PS. I did do a search, but nothing that could help with this specific question.
