[time-nuts] Has anybody checked this? GPSDO in kit

I just went and visited their website, and see they also offer a "kit OCXO"
from mostly through-hole parts and PCB. The OCXO insulation box is made out
of PCB, the thermostat is simply a jellybean TO92 transistor, and the 27MHz
crystal is an AT-cut being operated around 45C, so nothing awful
time-nutty, but still pretty neat that it's a kit. Details at
show that it walks about 14ppm during warmup and then might be good to a
ppm or so.
