Third party reporting/dashboard

Is anyone using a third party data analytics tool to create more attractive and/or complex dashboards and/or reports in conjunction with Knack? I've looked into Tableau but it is cost prohibitive due to the number of users my apps have (approximately 250 and growing). I paid a 3rd party to create a Google Analytics dashboard where I needed a quick turn around but doing that multiple times is not a long term solution either.

Thanks for any ideas you may have.
