I am looking for a new top of the line machine and have decided on E-trac. I just can't go back to Fisher. After watching videos of E-trac, I don't think I can take the wide-range multi-tone at first. Before I buy, can anyone tell me how the machine behaves in 3 or 4 tone?? Anything like other older machines such as cz series? I don't have access to a machine to try before I buy. Thanks....
