Having played around with several forms components, I settled quickly upon this one as it does everything I need with minimum fuss. It's very easy to get a simple form going out-of-the-box with a point and click interface, but it really comes into its own when you want to do something more interesting (GPG-encrypt all your submissions, perform numerous checks and transformations upon your input etc etc).

Very well supported by the author too. I had a problem with GPG deployment on my hosted server and Phil quickly (within 10 minutes!!) altered the component for me so that it worked flawlessly on my server.

Great value for money. Don't bother looking elsewhere in my opinion!
