Then there's the famous 'top speed' debate. Making a machine that is capable of running a 'demo friendly' job at speed is not all that difficult. So the top speed given in the brochure is pretty meaningless, unless you can achieve it with your type of work. Insist on running trials using your own jobs. Involve your own operators in the process. No one will be more capable of assessing how quick and easy the machine will be to make ready and run.
