The Nicolet is awesome. It weighs a lot and it's great to use, but I guess they are pretty rare now. Here are some exciting facts.
* For real time analysis I use a Hewlett Packard 3580B now - it has resolution to 1Hz and covers all audio. It doesn't do correlation and some of the other Nicolet tricks. A few hundred dollars.
* For non-real time I use a 96kHz 24bit AD converter that has a USB plug on one end. This is CHEAP. Goes straight in to laptop.
* Audacity software is something you should look at too. I think it's freeware. It does FFTs at 1024 pt resolution.
