I was using Polldaddy to do polls. Its very robust, but if you use the free version you can't export the results. When I found FSQM Pro, it seemed to do everything that poll daddy did, AND it let your export your results. The plugin is pretty easy to use, I made a form, it looks great, and it has tons of options. When I went to export, I could export the questions - not the results. This is handy in the event you made a survey on one website and you wanted to duplicate it on another, but not what I was looking for. For $29 I expected more. Here is a video. It's a great plugin, but for me I think an additional $10 for the exporting option is too much. Their support has me jumping through hoops to get their attention.
There is plenty of documentation and videos.
