The k-60 can do 4" and under side sewers and 1 1/2" to 2" lines with the smaller cable. It can do most of your work. A good top snake is of course needed for doing tubs like the ridgid k-39af. Most drums hold 125ft of 3/4" cable or 150ft of 5/8 cable. Beyond that you stuff more cable in the drum when you run out or keep a spare drum thats loaded around and switch on the spare drum.
