I would go with the Prince Neos 1500 with a Wise 2086. The portability of the Wise is amazing, it fits almost all machines, and you would have backup should the tensioner ever fail. Integrated Electronic machines are nice, but often you have to ship the entire unit in for repair or do some major surgery to get the failing component out. I am sold on the modularity you get with the Wise.
Also the new Gamma 6900 looks pretty good for a rotational gripper machine.
