The Wittern machines are the only machines I will buy. The machines are of excellent quality, and I seldom have had to do anything to them. They really stand by their warranties and are extremely helpful. Another reason I won't switch to another manufacturer is because I have 26 of their machines right now, which is significant enough that down the road when I have a lot more of them out there, eventually, I may pull some out of the field to use as "parts" machines. If I don't have 2 or 3 brands out there, it will be easy for me to provide my own parts when I need to, and as with anything mechanical, the day will come when I will need parts 10 or 15 years down the road.
thanks to all of you for your helpful replies. i think i'll start w/my barber as the 1st placement.
