Are you sure you wanna go for 3 wheel band saw?
^^^^^This. I was looking for a cheap band saw and bought an older Craftsman 3 wheel one off of CL. I could never get it to run that well and the blade kept coming off the wheels. I spent countless hours trying to get it to work, align everything, bought multiple tires, blades, etc., trying to get it to work and nothing made it cut as expected. Now it just consumes space in my garage.
