I've been using iNSA for a couple years now. Its still a little cumbersome to learn and understand, but it rocks, especially at this price. I especially appreciate the auto naming of songs and they are archived, so then I later know who, what, where, when, why but rarely HOW. I've also found it to be a better internet radio station search and listing, though often station broadcasts are not live at the moment. If I need to, I copy and paste the URL into iTunes (its rare that I need to go this workaround, however).
I also love that it records MP3 files at the same bitrate as the broadcast, so no loss of quality if tuning into a high bitrate station.
Once set and recording, I have been known to walk away and forget its recording, so I return to some pretty major volumes of stuff! That can be good or not so good. Trash what I don't like and keep what I do.
One other important comment in comparison to another similar product (not to be named here)... iNSA tends to prevent gap dropouts, though very short, sound like static. To edit these is a pain, but I rarely find them here. The only gap I have is just as it switches song titles, but its fairly short, and generally in a good spot to recover by editing.
