Hi BrettH Was a concern when we looked into them after all the stories of high maintenance on versions 1 and 2. Version 3 is no longer mechanical and is good for a million cycles, the machines are super simple inside and lay out is very clean. Any good tec would be able to service them. They also come with a brilliant online owners manual with video links to setting up the machine through to servicing step by step, really well done. Add in a well laid out service schedule outline, and I can't see any problems. I will take some photos of the internals to show the clean design. Chester
