Hello Murray,
 
the uBlox GPS are very excellent, yes, but their timing accuracy is still  
nowhere near that of the M12M. They also require external sawtooth correction to 
 achieve the stated accuracy. They do work better than M12's in a mobile  
environment, and are more sensitive.
 
BTW: I know of one company that has been shipping GPSDO products based  on 
the uBlox GPS' for several months now :)
 

The M12M and even the M12+ are still king of stationary timing  receivers as 
far as I know. Maybe Javad will have something in the  future that can improve 
upon the M12M?
 

bye,
Said

Living  where you do, I'd suggest checking out the U-BLOX range of
modules. The  model you need is the LEA-5T. The LEA-5 family is
state-of-the-art, and I  believe uses an ATMEL DSP software baseband
engine (with reportedly one  million correlators!)
