We have been Vantage dealers since the late 80's, and still feel that the Vantage system is a superior system.
We are told that there is no need to update the Infusion equipment that is installed, that any updates will be with software, UNLESS you are adding something that needs extra-ordinary memory, and then the upgrade to a new Infusion controller.
We have Qlink systems still in operation since 1990 with no issues.
BUT we also have either provided our refurbished Qlink controllers to many Qlink customers, and have provided upgraded systems to Infusion, as the Qlink controllers are just computers, and who has a computer that they still use since 1990??
