Yep, they are cheaper, work better and although they are DIY it is very
simple construction. I consider them to be "WinClocks" in the same vain as
"WinModems", except that this time you only use a handful of CPU cycles
and the benefit is that there is less circuitry between the clock and the
computer so you get better results.

Thanks to the generosity of Helmut I also have a HBG receiver as well,
though I needed to make my own custom antenna to get a good signal here in
northern England.
