Hello Paul,
 
thanks much for the feedback!
 
Yes, we think we have identified a nice combination of oscillators, GPS,  
and firmware that seems to work pretty well. The GPSTCXO units cannot be  
compared to a lower cost $150 Thunderbolt in terms of phase noise or  stability 
of course, and they have CMOS 10MHz outputs, but then the  TB's cost around 
$1500 new I guess.
 
We think the GPSTCXO's and LC_XO type units will work quite well  wherever 
standard OCXO's are used today, and power/size/weight are an  issue.
 
Bye,
Said

I have to say I was looking through the list of modules  that are available.
I guess a couple of things really jump out.
The low  power consumption and what you get in terms of behaviors. It is
pretty  amazing actually. Though I have my power sucking Tbolt and 3801.
But I  could easily see for a Amateur radio operator just getting into  time
nuttery that these might be a nice way to go. I guess that would open  an
interesting debate. Getting the used RBs at Hamfest of questionable  quality
for $200 or far less. Or something modern and simply  works.
Regards
Paul.
