I built one of these simple spectrum analysers, and it works well within it's 
design spec, however I find that I don't use it. This is because of the Wide 
Resolution Bandwidth, it is OK for harmonics and widely spaced spurious, but for 
in-close (<50kHz) measurements it does not cope.

With DDS and support chips now available at reasonable prices it should be 
possible to produce a performance spectrum analyser (including good IF 
filtering) at a modest cost. How about it Elecraft ?
