Granted, I am only a "prosumer" so I did not need to get a "professional"
grade analyzer.  I have to say that the $200 WiSpy v2 from MetaGeek is
good for people like me who don't need (or can bill for) spectrum analysis,
and the WiSpy 2.4 @ $400 is even better with higher resolution, faster sweep
times, and external antenna.  I could not find any decent gear for less than
2K when I wanted to "sweep" my house for 2.4G noise, and the WiSpy gear fit
the bill.  And they are both supported in Linux via the Kismet project!
