How about a cheap Android tablet and a clock application? I assume 
you're planning on AC power, since LEDs won't run long on battery.

Sellout.woot.com has a $60 tablet, and it's not hard to find them under 
$100. According to the manual, "If Sero 7 connected with a Wi-Fi, you 
can also select use network-provided time." While not strictly WWVB, if 
you only need 1 second resolution, NTP should be fine. This also assumes 
you have WiFi available.

You can probably find a 10" one for <$100. If you stretch, I've seen 
refurb 1st gen iPads for $150 (pretty sure these can do NTP, too). The 
real cheap tablets tend to have poor digitizers, but that really doesn't 
matter for use as a wall clock.
