I don't want to start a war with this BUT almost all the these opinions are done by people with the desire to buy new machines or sell new machines. Over one half the machines in my two shops were purchased new. The new machines are no faster or productive than new machines. In fact, last Friday I talked with a shop about doing some work for them because they are unable to cut some parts efficiently on their NEW machines. I will put the parts on one of my old machines and take about 60% of the time out of them and make better parts. You can buy new or used, how you use them is the critical issue. Again - having some fun now Stuart
