You can put together a GPSDO system with 10 MHz output for less than $200.
Here's just one example:
Ebay item # 290322053618 By buying the items separately, you can sometimes
do even better on price.

The Trimble thunderbolts are very popular because a lot have been pulled
from mobile phone tower sites during upgrades. I use one here to phase-lock
my HPSDR system and it works well.
