I'll pipe in here, as we use express scribe at work. It works flawlessly, but there is one MAJOR design flaw. It allows you to open as many mp3's as you like, but every time it opens one, it converts it to a wav file. As we deal in council meetings that can last 6-7 hours, the files can grow to larger than a couple of gigs. Normally, not an issue, but on more than one occasion, the secretary's computers started acting strangely, until I noticed that they had ~10 Megs free on the HDD.
