[hpsdr] New entry in the (almost) SDR arena

[George & Jean]

I agree! I'm new to this whole SDR/DSP thing and sorta fell into it while I
was getting back into homebrewing tube stuff! ;-) I played with the SDR-1000
demo and was HOOKED! Since then, I've built the SoftRock and am in the
process of building the R-2 Pro as well to compare an analog front end. In
the meantime, I bought the FA-66 because I wanted the best on the backend.

Alberto,

Here is another way to think of it:  When someone buys a SDR-1000 they
usually also buy a good sound card like the D44 or the Edirol FA-66.
Flex sells the D44 for $159 and the FA-66 for $350.  Basically they
are paying $159 or $350 for an ADC to use with the SDR-1000 (or even a
SoftRock!!!).  If you look at it this way the $95 for a LTC2208 130
MSPS ADC seems pretty cheap.
