That's not correct.  LP-Pan = $225 (assembled), E-MU 0202 = 
$199.95 (list) ... total $425 vs. $499 list for the SDR-IQ.  
The difference in "street" prices will vary significantly 
deepening on shopping skills and the availability of used or 
kit options.

LP-Pan with the E-MU 0202 (USB) soundcard, LP-Bridge and 
one of the PowerSDR versions are resource intensive for 
the computer.  SDR-IQ/SpectraVue have much more reasonable 
CPU requirements.  

Unlike PowerSDR, SpectraVue will operate in a Window and 
can provide simultaneous spectrum/waterfall displays. 

Although not important here, SDR-IQ also supports a broad 
range of non-Elecraft transceivers.
