Looks like the chineese have finally gotten around to copying the K-60.
Looking at the picture on e-bay from craig's affordable tools there is a pipe drain cleaning machine called ths STD 125.
It looks like the old style projector box K-60 buy it has the capacity of the K50 it uses 5/8th sectional cable and you can snap on a small drum on the rear of the unit. It is probably total junk. Has any one seen this unit before or used it ? Thanks David
