Opinion on oscillator accuracy

I'm looking for opinions and I know what that can cause. I have my standalone WSPR transmitter working minus a PA but I am going to build a few more for some friends. I have some standard GPS boards but I was wondering about using a GPS stabilized oscillator for the DDS-30 and the PIC. If you have experience with the PIC/DDS-30/DDS-60 combinations, please give me your opinions on instability and what it might cause. I can do a GPS stabilized oscillator reference but if that isn't a problem, I probably won't add the hardware. These units MAY be outside where they could experience some pretty wide temperature variations here in Texas so what do you all think?

Thanks,
