The fact is that if you buy something that has some moving parts, for continued usage it will probably demand service. That brings you to a hard fact, there are two kinds of service, bad service and good service.
I was a service engineer for a large computer company for 47 years. I never left a machine unless I personally felt that it was serviced right. I prefered to do the job right the first time. I found out early it was better to run machines rather than having them run you. Customers can see and know if you do your job right. It was amazing to me to see how many customers wanted me back when I worked in another guys territory.
