We were working with a 3rd party vendor who created a custom materials collection website for us. We stopped using the tool because of glitches. It had very limited features and we didn't want to pay the amount to keep updating the system.
Wufoo was so much slicker than the tool we used and we had the ability to create our own forms (unlike the other tool which relied on a developer to make the updates). We also had access to pull reports which was a bonus.
Wufoo is an excellent option for someone looking for a basic form which allows them to collect data for various reasons (survey, transaction, entry form). The tool is super easy to use and requires no HTML knowledge. Wufoo has excellent online tutorials, many with videos to help beginners. Also they have a blog with tips and tricks to keep the hardcore users happy.
