The only thing I can think of is to try GEMM http://www.gemm.com.

They don't list items as SACD, just CD or vinyl, but there were some in the $50-60 range. I don't know if that's too low for that item, but you might want to email the seller and see if that is the one you are looking for.

I'm sure there are some sellers on gemm that specialize in hard to find stuff like that - you might find one and ask him/her to keep their eye open..

Good luck!
