I am the author of the library. Let me comment about the pricing - for me personally, all the alternative hosted solutions (like Geckoboard etc.) where too expensive - by paying monthly subscription fee in a long term you still pay much more, than once buying any licence of FinalBoard.

There is a trial version available where you can download and test it out and see if it fits you.

I set minimal price for Basic license and on my opinion this is fair price for what you get. In basic license you get unlimited dashboards, unlimited widgets with all the benefits FinalBoard offers you - you won't see such price on any on hosted solutions even close.
