Have you searched at all?
In vt_mav's post #556 in this thread, just from yesterday, had a pair listed on ebay. Auctions ended, but doesn't appear they sold...so if I were you, I'd send him a message thru ebay and see if they're sold. That was a very reasonable price, but one does have a gouge/scratch.
Also, consider calling Merlin, I'm not sure if they're still available or not.
If you pick up just one good one, then chances are pretty good you'd be able to find another in a junk yard or thru some member here.
