Best USB stick/device as Spectrum Analyzer for <= US$ 500

It should arrive today at the work place, where I am at tomorrow and Wednesday....and bringing it home then...so first comparison at Thursday first...

I also can't wait to compare them ;-)

BTW: Anyone use the tracking generator together with the SA44B?
From the specs it should be possible to do a frequency plot of the audio spectrum as well?

I have both the SA44B and TG44A, but only used it in the MHz range...

[davorin]

And is it worth the additional cost of the tracking generator?

But definitively something to try out if I get a TG44A...
