I'd happily recommend Turbotax to anyone. It's simple, use and easy to understand.
My only complaint is that there were times when it was hard to read the text on screen, this is probably because my monitor is set to a black screen display, IE white text against a black background. But some of the pages on your site still had black text against a black background, so I had to highlight the text to read it.
I'm probably in the minority for using black screen but its something to think about.
