If money is no object... get the Servo... I have had 4 different industrial machine but all had the clutch motor. I think you can set one up to go slower if you want to. The one I have now is so gradual and I love the control. If I want to go fast I have to really tromp on the foot control - then look out... I guess my question would be how much does it cost to put in a Servo? How much and how often are you planning to use it? Will your projects be a lot of stop and start? While it would be very nice to have on there, I would hate to spend a lot of money on one and then not use it much.
