[EX Q]: I don't know why this flour isn't available in grocery stores in the Midwest.  Typical grocer flours have a protein content much too high to give an authentic taste to such foods as pizza crust and homemade pastas.  And after years of making homemade pastas and trying to find that perfect recipe that would result in those served in the best Italian restaurants in the US and Europe, I'm happy to discover, the secret was in the 00 protein content all along.  What a fabulous difference this flour makes!  Freezes well too.

[EX Q]: This Icicle performs flawlessly with very good audio quality for my audio-technica cardiod condensor mic.  Took me a short while to figure out the little silver button on the side wasn't a button, but instead a rotational knob for setting the gain.  This device literally plugs into your USB port on a Mac, you adjust that knob, and your done.  You then can forget about the device and enjoy flawless audio performance out of your mic.  This beats the hell out of the more expensive FireWire solutions I had used before.
