I looked at the ebay listing and it looks like it would be good as a 
106.5 MHz signal
to lock another oscillator to get a 10.244 signal for a 10GHz convertor. 
The second
oscillator would clean up the close in phase noise and your circuit can 
be locked to
a 10 MHz signal of whatever quality  needed.

Don't know if you can produce them at $40.00 or so but I would be 
interested in what
you come up with
