Me? :) I got my RPR back in 1981. I worked in Florida for ten years. Florida has no requirements, so there was a lot of competition. Last year I got my manual machine out, cleaned it up, and started practicing. I am now hitting 210/225 fairly decently. I have DigitalCat Student - and am now on computer (sort of). For me, the hardest part of getting on CAT was the mentality of doing it.
Speedbuilders is the cheapest way to go. Pay $30.00(?) for twelve weeks of dictation. Order what you want, you get three takes a week. I have mine saved in a file in my Yahoo account and I downloaded them too.
