There were couple WWVB threads recently.
One of the questions was if the La Crosse UltrAtomic 404-1235UA-SS wall
clock is still the only WWVB clock that uses the new BPSK format. I
learned that 3 different companies made prototypes but only La Crosse
went to market. So at this point the 1235UA is the only commercial clock
using the new eWWVB format. Everyone who has one reports superb
reception quality, far better than traditional WWVB clocks.
Another question was where to get the bare Everset ES100 chip or dev
boards. The original Universal Solder PCB with ES100 has been out of
stock a long time. It's the one seen at
http://www.leapsecond.com/pages/es100/pins.htm
The good news is that Universal Solder just announced a newly designed
board:

Your choice of bare 12 x 16 mm board or a full Arduino-based dev kit:
