Have you tried to build your own oscillator? There are a few companies
that still sell single crystals. If you could piggy pack on some bigger
customers production, you should be able to get the crystals relatively
cheap. All you then have to do is to design an approriate, low noise
oscillator. If you can relax your frequency specs, ie if you don't care
if you are off by a few ppm, then you could scavenge the rejected crystals
from said big customer.
