There's tons of vcxos from Digikey.. just searching for VCXO and 
restricting it to 10 MHz turns up about 17 parts.

choosing the first one in the list

50ppm pulling range

This happens to be a ceramic resonator, so the close in noise is 
probably not so hot.

But some checking at Digikey and Mouser and the like should turn up 
soemething.


How about an Abracon ASVV series SMT at 20 MHz for $2.98 Qty 1?

or a VCTCXO AST3TQ-V-10.000MHz-28 for $19.25 Qty 1 from Digikey.
280 ppb from -40 to +85
10 ppm pulling range..


Abracon is in southern california, for what it's worth.
