I went to the Shelby Hamfest today and met Sam from 3dbSDR. He was offering an assembled SDR for $100. After talking him to death about SDR and noting that it didn't say "Collins" or "Hallicrafters" anywhere on it, he demonstrated it for me.

This thing was awesome. I'm going to get one. This is better than internet porn. This is a 1.8 - 30 mHz receiver - only system. They are working on a continuous coverage receiver to 1 Ghz.
Please note that I have no connection whatsoever with the company and I don't receive any remuneration whatsoever from your purchase. I'm not giving up Collins, Icom and Hallicrafters, but this thing was neat to operate.

Well Labview, I've been looking for an affordable way to dip my toe into the SDR waters. Thanks for the heads up. I will pre-order one of these also. That way, if I likee, I will spendee more later on. Who knows. Mebbe even Mr. Fansome will be tempted by this...

What surprised me:
He has a short antenna up, and the freq he was on was receiving some splatter from another station. He just grabbed the skirt of a filter in a window and moved it down a bit - splatter was gone!
It hit me while I watched the "spectral" window - I can use this thing as a test instrument!
Now, I'm all about setting at me desk slowly twisting the dial on a receiver - and there isn't much better than the smell of dust cooking on top of a 5U4 vacuum tube - but this was awesome. I was thinking - I've done a lot of microcontroller programming - maybe I can put a knob on an "L" bracket and every time the micro sees a pulse from the encoder, it sends a virtual "frequency- down - arrow." A real radio has knobs, after all.

Anyone know if this sdr will work w/ any of the *nix flavors?

It does not work with Raspberry

Ths Softrock Ensemble II SDR receiver kits are also a very good deal at $68. You just have to be able to assemble them yourself. They cover the same frequency range. This may be one of the best entry-level SDR units available.
