MultiPage Survey is quite good out of the box.
There's a bit of a learning curve to grasp the application, but the user manual helps. Great routing features for questions that need to branch out. Awesome with incorporating images and even video to the surveys. Quick tech support resolutions.
Survey results export to basic delimited data formats but don't feature statistic reports or cross tabs. It also doesn't support a textarea field for paragraph format inputs at this time.
Overall, it is a quality product for USD 34.95.
