I’m always looking for some kind of online survey software that allows for complex branching, easy data export, and – most importantly – is cheap. Looked at a few packages: Perseus, SurveyShare, etc.
I recently explored SurveyConsole Web Survey Software with their 30 day trial offer. It’s easy to work with and can be used with complex surveys, but many of the nice features in the trial version are not included in the $29/month basic version. Still it’s a solid product which is very affordable.
