Tony,

the most important difference between SDR-IQ/-IP(from RF Space)
or Perseus and the $200 SDR on
http://www.lazydogengineering.com/LD-1A_SDR.html
is that  the latter is no direct sampling receiver.
It uses a downconverting technique with a number of shortcomings,e.g.
phase noise of the LO and others.
I would go for a direct sampling SDR like those e.g. from RF space or=
=20
Perseus.
