I just received the Heol Design N024 Trimble ACE III clone to resolve the week rollover problem we have been experiencing in the TS-2100's with the original Trimble ACE III gps units. Installation was very straight forward taking about 5 minutes. On a cold restart I had "Tracking" within 40 seconds with the correct date and time (Leap second issue also resolved) and "Locked" with my new OCXO in ~20 minutes. Once locked I did notice something interesting but maybe not important. The control voltage to the oscillator (timing > util > tfp 0) went from a very consistent 0xba6f to a 0xbb02. That's about 0.2% of scale. I'll watch it over the next few days to see where it settles in.
