Has any other school shops tried to use a shopbot? We purchased one 3 years ago and have used our's less than 40 hours. Our experience has been it is not user friendly and the manual is all but impossible to understand. We have had several very knowledgible people try and figure it out without any luck. We are going to sell ours and look for a machine that is reliable and user friendly. We have had nothing but problems with ours and when asked, I have had told other teachers not to purchase a shotbot but to look else where.
