Communication Apps

I was looking for a communication board type app. Someone recommended proloquo2go but it is $220!!! I need free or at least pretty darn cheap. Any recommendations?

 

Check out grid player. Awesome and free.

 

I've used Sonoflex, and there is a free lite version that was pretty robust, and it looks and functions like Proloquo.
