John, please post info on the crystal when you have it. And if a
quantity purchase gets a better price, there are probably several of
us who might help get the order quantity up.

I think I have found a supplier for a 32.800 Mhz crystal, which
would put the softrock at around 8200 and make it a more reasonable
15000hz offset. I hope that this will still be far enough away from
the 8215 IF to not cause any problems, while making the bandpass a
little more symmetric.Someone else had mentioned the use of a
HPL-4562 opto-coupler to provide more buffering for the softrock. I
may order one and give it a try. If it works, a crystal even closer
to the IF may work without causing problems. Of course, I won't be
able to test any of this until my K3 arrives, hopefully in December
as I am in the first batch.
