[hpsdr] Phoenix - footprint for high performance crystals

I have gone for the discrete oscillator as suugested by Grant Hodgson and Chris Bartram. One of the issues would be 
cost - how much are these devices?
Also the discrete circuit will give the best possible phase noise performance with a practical circuit as I 
understand it.
