For what it is worth the folks at Radical RC have a crystal exchange service. The cost is $5 per crystal, which would probably be less than the cost of servicing the radio.

They also have reasonable prices on other items they sell, freight is reasonable and they have been professional in all respects. I am consolidating transmitters and expect to receive four crystals for three brands of receivers next week.
