I use transcribe all the time. I'm also a pretty accomplished Logic user. For what transcribe does, it does very well. The interface is simple and straightforward, it's relatively easy to dive right in and begin using it and it's inexpensive. Very little in the way of a learning curve but a pretty powerful app. There's a couple of interface issues - i.e., things that should be shortcut key enabled but aren't - that will make you second guess the app, but overall it's a good deal for the money.
Just my $.02 worth...
