Formidable Pro is the single best piece of software that I have ever purchased. Hands down the best 97.00 I've spent on software.

I looked at Gravity Forms, Contact Forms 7 and Formidable before settling on Formidable Pro. Aside from having a lot of features I was looking for and being pretty easy to deal with, the 2 things that won Formidable for me in the end was having a free version that I could try and the tremendous support that Steph provided @ strategy11.com forums before I was even a customer.
