I just finished with model talker. Recognizing that it is still in beta testing, it was still a frustrating experience. The program randomly shuts down after you have recorded only one two or three sentences. Then you have to go through about 10 steps to open it back up. Maybe it was just me, I don't know. But I'm glad just gotten through 1600 sentences and am now waiting for them to return the results to me. I started this back in June and just finished this week. I took a long time off because it was so frustrating. But I decided that it was something that really needed to be done, and when I got dedicated to it, it really only took about three weeks to finish. And I worked on it about 30 min. a day. I would suggest you take a look at it and see if you think it's for you. I did have to buy a different headset, Sennheiser, that cost about $150. Good luck with what you decide!
