Try calling East Coast Parts. I have had good luck with them.

I've been buying crystals from:
M H Electronics
9569 Ninth St.
P. O. Box 652
Rancho Cucamonga, CA 91730
(909) 989-1976
They have made crystals for me at $9.60 each, plus $3.50 shipping
PER ORDER. For two channels, that works out to $41.90. They usually
deliver in 2-4 weeks.
Good Luck,
