New Droid App question

I have only had my Droid for less than 2 weeks, and have seen some info/posts on different apps available, but I would like to know what might be a good 'speak to text' app. It would be great to not have to put my glasses on everytime I need to see something small, which is a lot on the Droid, I am finding out. So I am looking for what others might be using, and recommending for a app that has a lot of function for the times it would be easier to "speak" than to 'hunt and peck'. If I had to pay something, I feel that it would be worth it to have something that would work for me.........
