If you only need one constant frequency, it is practical to order a
custom-ground quartz crystal.  This costs about $10.00 and 1 or 2 weeks
for delivery.  Though the cost may be slightly higher than some other
way, it is definitely a small, low power, and simple to design solution.
As for where to buy the crystal, I have had good results with ICM.  I
don't know if they're on the web or not but they should be at (800)
725-1426.
