That is a really good question. I'm happy building my own, but there does seem to be a gap in the consumer-type products available. I'm in the same camp as CB, haven't noticed any but haven't gone looking particularly either. Still, seems like I might have seen something. I am starting to notice inexpensive clock radios that evidently have battery-backed RTCs in them. Don't think there were any extraordinary claims to accuracy, though. Maybe the average consumer isn't all that worried about accuracy. Clocks that derive their timing from the AC mains actually have very, very good long-term accuracy, but won't necessarily be within a second or two at any given point. And then there are power outages to deal with. There has also been some talk about changing the way the grids are managed that may affect the accuracy of mains-synchronized clocks, I'm not sure where this currently stands, however.
We have several of the WWVB-controlled radio clocks here, too. Being in Michigan, the signal from Fort Collins isn't terribly strong, but they work quite well. I believe they are programmed to synchronize at night when propagation is favorable, but in the fall when we change from daylight to standard time, this usually results in a few missed syncs, not that it matters much.
So the radio clocks seem to be the consumer-oriented solution for accuracy, although they don't necessarily work well everywhere as you have noted.
