Hi Damien,
THSC also used Q-Matic as well until we relocated to our new building, we now use SmartQueue which is the system used in RMS Branches across NSW. 
After some initial teething problems with the virtual callers and reporting we have gained some expertise within the team to manage the parameters and configuration, we are able to pull the required reporting from the system. 
We are now evolving towards having a Concierge service using an iPad so customers can obtain a ticket from the kiosk stand, from the concierge or by walking up to a CSO at the front counter.  The ticket kiosk is a Falcon 1000 which is fairly standard, paper is thermal and easy to obtain.  Cost of equipment and set up is competitive, after market service is good.
